The style of art in this movie is very visually appealing, and the characters are all fun and relatable. The story is based in an alternate version of earth on which we, viewers, must suspend our disbelief, because the Earthlings are strange and cartoonish--even animal-looking (one character is a person with a flaming skull for a head). I really enjoyed the nonstop action and art direction in this film, and the voice acting was great too.
