Fantastic cartoon production. I do not know, since, everyone has their own taste that is so particular to a genre, that I do not know if you would like the music I listen too, but there is no way you will not like that high quality cartoon The Day My Butt Went Psycho! ! I don't watch many cartoon online in cartoon category, but this one was amazing. It's really hard for me to separate best from favorite. With best, you really have to distinguish what makes it important. Taking into consideration the influence it brought to the medium, be it with writing, direction, cinematography. I re-watched the beginning last night and kept saying I'll watch only one more scene until I was over an hour into it. I forgot how good that cartoon is. I love how music just is the pure soul of that film. This cartoon is great but I will say no more. Anyone who has seen it will agree with me I'm sure. The action, special effects, characters and score are all perfect to me. This director is great. With The Day My Butt Went Psycho! online he seems to be setting himself some kind of a test - how far over the top can he go?
