Adventure Time is a short form animated series by Pendleton Ward. It follows two main characters Finn the human and Jake the shape shifting dog. It has a massive following of viewers, and it has hit Netflix streaming, so I decided to give it a try, and it is amazing.
Each episode gives Finn and Jack some adventure to go on. Like ward off candy people zombies, or go deep in to some forest to claim some magical object, but the shear randomness of the villains and allies they meet, and witty dialog make this show funny to watch. This show does more with twelve minutes then some shows do with forty-four (length of an hour long TV episode), and it always puts a smile on my face.
It sounds like the voice actors must be having a good time too. Long time voice actor John DiMaggio plays Jake, and if you think he sounds like Bender from Furturama then you would be correct, and relative newcomer Jeremy Shada plays Finn, and he is about the same age as Finn in real life.
If you need something to make you smile and laugh, and not have to worry about it getting all dark serious, then Adventure Time should be on your short list.
