I watched Funky Forest: The First Contact (
imdb) the other day. It was pretty entertaining and featured some kick arse music, especially at the end.
If you like brainfuck films such as Holy Mountain, El Topo, Tetsuo: The Iron Man, Eraserhead, eXistenZ and Brazil, you'll probably enjoy this. However, this one doesn't have as much offensive stuff in it as the ones mentioned.
