I love Adventure Time in all its iterations. 
The cartoon is consistently irreverent, poignant, surreal, and most importantly, hysterical pieces of animated programming on television. Ryan North's Adventure Time comic series manages to capture everything great about the TV series and expand the universe in meaningful and unique ways.
Hell, Adventure Time: Hey Ice King! Why'd You Steal Our Garbage?!! may have been brief for a full-priced 3DS game, but it was still a ton of fun. Adventure Time: Explore the Dungeon Because I Don't Know, not so much. This agonizingly boring dungeon crawler was bereft of any of the charm and humor that has made the show such a success. Repetitive dungeons with cut and pasted enemies that all seemed to be colored from a palette that consisted of blue-grey and slightly less blue-grey, only added to the redundant nature of the game. 
Sucks. We really wanted a longer RPG-style Adventure Time title and what we got was a cut and pasted mess.
