Best cartoon of the decade imo. The show got better and better as it grew up with the audience. The characters grow and develop, the different and unique stories remain innovative and intriguing throughout, and the animation gets better and better. Not to mention the smaller touches and details that just serve to elevate the show that much more. The music is phenomenal and in most episodes the sound design is fantastic and makes the episodes atmospheric no matter the events. The backgrounds are phenomenal and only improve as the show goes on, some of the backgrounds can tell entire stories that the viewer can interpret and it can add even more depth to the show. Adventure Time is also a perfect example of how to make an episodic show with overarching stories and elements, as the show is episodic, but there is continuity and some story arcs that don't clash with the overall nature of the show, unlike in other shows that attempt to do something similar like Steven Universe. And lastly, this show made the absolute perfect use of it's 11 minute format, most shows with big story elements are 22 minutes like Avatar or Gravity Falls, but Adventure Time uses the 11 minute format as an advantage rather than as an excuse to brush off comments regarding mediocre storytelling or writing that other shows like it may receive. No show is perfect, but Adventure Time is pretty close, and I can't think of any other cartoon this decade that's left quite as much of a positive impact on the industry as this one seeing that it practically revived TV animation after the atrocious year that was 2009. Overall this show is a dramatic, introspective, fun, interesting, meaningful, and impactful journey that is well worth taking for anyone interested, and it's my favorite cartoon of all time as of 2019. Very highly recommended.
