Amazing, I'm still stunned =)
So we follow the story of a little boy who is.. and his frieds that consist of.. Well, just anything is hard to say in this.
The randomness is sometimes disturbing but in a calm manner, ulnlike "metal gear awesome" where you could miss out some work in fast paced scenes. Although some scenes are obscene I don't think they really cross the line there. The confusion on this works and in the end you might even start to think about the logic but then you find out it is not necesssary.
Graphics are kind of childish but thats a plus, combined with excellent framy-by-frame animation. Music.. soem background might be good but I didn't miss it - you can concentrate on the events. For me it was humorous but I'm sure it can offend some people.
Overall it's is a great content but only because of its originallity. Now it would be a hard task to make a better one and just a longer animation may be unbareable with the same style.
So I'd say this is a classic to be left as it is=)
PS. If you didn't then pay close attention to subtitles =)
