Hard to say. I would say Weight because of the skiing, but in all honesty, Level 1 and Poor Boyz had more of a fun theme to them. Weight wasn't going for a theme, which is fine because Stept goes for the raw outlook on city skiing and it always impresses me, but I liked the circus theme of Poor Boyz. The Grand Bizarre definitely had a few yawns in it, but solid film for sure. After Dark had a sick theme and everything was ill, but it was the same stuff as Eye Trip in my opinion.
No one seemed to do it perfectly for me this year, but that doesn't happen a lot so no worries. Overall though, all 3 of those films were fucking awesome, just not perfect like certain films have been.
