2 days and ~40 posts later, seems kind of odd for this bunch that it didn't even get a cursory nomination.

BUMP

Sci-Fi: BLACK MIRROR: THE ENTIRE HISTORY OF YOU
Through-provoking sci-fi about how future techology might influence human relationship. (I give SLEEP DEALER a second place.)

Musical: MEMORIES OF MATSUKO
There are other contestants (HAPPINESS OF THE KATAKURIS, THE FORBIDDEN ZONE, CANNIBAL THE MUSICAL, STINGRAY SAM) but MEMORIES OF MATSUKO wins because it manage to tell a uplifting and heartbreaking story and combine this with mindbending visuals.

Animated: REDLINE (2007)
Scifi racing anime with furries in it. This doesn't sound awesome, but it is. Turn off your brain and enjoy!

Comedy: STINGRAY SAM (2009)
Cory McAbee's space western serial is one of the few watchable modern comedies. At the same time it has loads of artistic value - unlike laugh-porn such as scary movie IV. The first Stingray Sam episode can be watched here: https://www.youtube.com/watch?v=4S4N0lthxmU

Action/adventure: JOHN DIES AT THE END (2012)
Anarchistic and insane supernatural action-comedy, faithfully adapted from the original novel. Pure entertainment.

Horror: SHUTTER (2004)
Nothing even remotely original in this thai horror. But this movie scared me more than any other. So it wins over SUICIDE CIRCLE and UZUMAKI.
