Saw Step into Liquid at the Angelika Theatre in NYC when it came out. Didnt care for it so much...some nice photography for sure but i thought it was a little soft...or, i dunno, made for family viewing. Maybe im being to harsh on it...I better see it again
Riding Giants, I think, is the BEST surfing film ever made. Well crafted and the story development is well done. The extra feature with Stacy Peralta re: the making-of the film is quite good too. The Mavericks portion is my favorite
Some of my other favorites are:
SUPER SESSION
