Ten Amazing Modern Animated Series.

having already made a list of ten amazing animated series from the 21st century.
( http://imgur.com/gallery/1920x ) I quickly realised that limiting it to ten simply did not cover the grounds of conveying the quality that the last 16 years have brought us. So I'm extending this up to 25, by adding 15 more series, for the most part these series aren't QUITE as good as those in the other list, but are still well worth watching, the one exception is the final show on this list which in hindsight really should have been on the first list.
anyway, here's 15 more great series to watch,

Samurai Jack (2001-2004)

Samurai Jack is the Story of a Samurai who, in his last stand attempt to defeat the evil Sorceror Aku who is threatening his land, is instead defeated by the sorcerer and subsequently trapped by him in a future where Aku has more or less claimed absolute victory.

Samurai Jack is a fascinating series to me, because whenever I see a TV show, movie or anything else get too long-winded with dialogue and exposition, I think of this series, a series that managed to convey ninety percent of it's story with only sparse lines of dialogue.. the creator, Genddy Tartakovsky had some hits before this show aired, like work on Powerpuff Girls and creating Dexter's Lab, but this was his playground, he had found his niche, in epic, subtle, action-packed, and stylistically brilliant visual storytelling, Only let down by it's lack of an ending, Although that soon may be rectified. with the series being resurrected this year, hopefully to good effect.

The Legend of Korra (2012-2014)

A follow-up set 70 years after Avatar: the Last Airbender. Legend of Korra tells the story of Korra, a teenage girl living in a world where people can freely manipulate the classic four elements, However Korra is the Avatar, the only person in the world who can manipulate all four. with this power comes the duty of maintaining balance amongst the worlds populace, but is it a world that has outgrown the Avatar?

In terms of actual animation, nothing here can rival Legend of Korra, the production quality of this series is STAGGERING, with animation and music that rivals even the best anime coming out. but that's not all it has going for it, it has great characters, absolutely AMAZING action, intelligent and worldly relevant issues in its plots, and is brilliantly directed and well-written to boot, I'll admit that the first season and a half can be a bit hit and miss, but by the start of season 3 it DEFINITELY found its footing. It still doesn't quite eclipse its predecessor though...

Adventure Time (2010-Ongoing)

I'm not gonna even try to write a premise for this...

I can definitely understand looking at Adventure Time and dismissing it, hell I did too at first, it looked like a series that was trying way too hard to be zany and random, as such I avoided it, but upon actually giving it a try I found myself routinely impressed, this series is bizarre, it's confusing, it's random and it's zany, but it has (bizarrely) has AMAZING continuity and world-building in spite of its random nature. and it also continually hits high notes with its comedy, and even manages to engage on an emotional level. It's the evolved and refined form of Spongebob or Ren and Stimpy, with all the randomness being tied together into something that's deceptively intelligent.

Archer (2009-Ongoing)

Archer focuses on the exploits and misadventures of Sterling Archer, a chauvinistic, narcissistic asshole of a secret agent working for the intelligence agency ISIS (not that one)

If it's pure comedy you're after, Archer's your best bet, the writing in this series FLOORS me with how sharp it manages to be, and that sharpness is accentuated by expert comic delivery, H.Jon Benjamin in particular kills it. the premises are funny, the dialogue even outside comedy is genius, the characters are consistently entertaining, surprisingly not falling into flanderisation like many animated comedies do quickly, it's a laugh riot.

Bob's Burgers (2011-Ongoing)

A show set around the exploits of the Belcher family, a family of five who own a small apsiring-to-be-greater burger joint in a small sea-side town.

Another show featuring H.Jon Benjamin, Bob's Burgers doesn't quite match up to Archer in comedy, but it balances it with incredible charm, the main cast is EXTREMELY likeable and the comedy scenarios are simultaneously creative and bizarrely well grounded,, I'd pretty much call it the animated version of Malcolm in the Middle, as even when you aren't laughing, the character relationships and dynamics are so intensely endearing regardless that you'll start watching for that alone, with the still brilliant comedy as an added bonus..

Steven Universe (2013-Ongoing)

Steven Universe tells the story of Steven, a young boy who takes his late mother's place in a group called the Crystal Gems, a group of superhuman alien-ish beings whose main goal is seemingly to protect human life while also cleaning up odd occurrences here and there involving mysterious hybrid creatures. although the true nature of the Gems may be far.. far more complicated.

A lovely creation from the mind of Rebecca Sugar (formerly a lead writer of Adventure Time) Steven Universe takes Adventure Time's strengths, multiplies them and In my opinion ties them to much better characters and issues, it's constantly beautiful to look at and listen to, it has stellar voice acting with great music and character design but it's the surprising touches of really deft drama that elevates this series. it touches subjects that 90% of cartoons wouldn't go near with a seventy foot pole. it tops all this off with incredible world-building, characters and a tangible sense of likeability.

Rick and Morty (2014-Ongoing)

Again, I'm not gonna even try and write a premise for this one, I can't do it justice.

Rick and Morty is a prime example of how even adult cartoons have now entered a golden age, alongside Bob's Burgers and Archer, and the everlong South Park we now have four running concurrently that are actually REALLY worth watching, I don't think that's ever happened before... but anyway, Rick and Morty's strengths lie in its deft writing, it's able to switch fluidly between its often incredibly dark sense of humour into surprising moments of pathos with ease. and it punctuates this with a marvelous sense of creativity, the character interplay is constantly brilliant, and despite its somewhat limited animation it still manages to be visually appealing through its design and framing alone. this one's hard to describe, but it's not hard to watch, it's one of the best on this list.

Gravity Falls (2012-2016)

Sent to stay with their Uncle throughout the course of the summer, twins Dipper and Mabel Pines soon discover there's far more than meets the eye within the town their Uncle calls home.

Set to end in a couple of weeks time, I know I won't be the only one who is really... REALLY going to miss this series, the comedy is brilliant, the music and animation are brilliant even in their simplicity, the plot is brilliant, yep, despite outward appearances it does have an overarching plot with a mystery interwoven into seemingly episodic ventures, but the thing that sells it most is the characters, just like Bob's Burgers I could just watch these characters interact with each other all day, they're that funny, and that likeable. one of Disney's best TV shows ever, and probably the funniest thing to ever air on a childrens network.

Over the Garden Wall (2014)

Two brothers find themselves lost in a mysterious land and try to find their way home

That is all I'm willing to say about this series, besides the fact that it's utterly spectacular. this is just one of those series where it's best to go in nearly completely blind, trust me, you won't regret it.

Avatar: The Last Airbender (2005-2008)

In a world where people can bend one of the four classic elements to their whims, the Avatar is the only one in the world who can bend all four, with a hundred year long war desolating the world the duty falls to the current Avatar, a 12-year old boy named Aang to master the elements and restore balance to the world.

This isn't just the best animated series of the 21st century, this is the best animated series ever made, and probably one of the best TV shows ever made.
think that sounds extreme? fuck you, it isn't.
ATLA combines all of the strengths of the shows above into one glorious package with a little bit more on top, it has the brilliant comedic chops of Gravity Falls, the deft drama, subversive nature, and clever world-building of Steven Universe, the genuine and commentative social issues of its predecessor Legend of Korra, the sharpness of the dialogue of Archer, the amazing, warm and familial character interactions of Bob's Burgers, the deft ability to balance tones of Rick and Morty, the incredible continuity of Adventure Time, and the incredible visual direction of Samurai Jack all added to a running plot framework of 60 episodes all building through phenomenal pacing to one of the finest finales a show could ever have.
This show... is a MARVEL... it has one of the best core casts I've ever seen, with 6 main recurring characters that are each individually strong enough to carry a show by themselves, incredible antagonists, amazing production quality, and a remarkable level of nuance for a show that was originally broadcasted on Nickelodeon... I cannot begin to describe the number of ways this show succeeds... but judging by the reverence I've seen for this show on Imgur, I won't need to. this is simply put, a masterpiece.
