The Last Blockbuster - I didn't think it was particularly good, but I still enjoyed it for nostalgic reasons. Still, I definitely don't miss Blockbuster as much as the people in this documentary.
Momentum Generation - I enjoyed this way more than I ever thought I would. It was focused on Kelly Slater and a lot of other professional surfers. It was partly about surfing, but they also had interesting lives and were very honest and sharing in the interviews. You probably won't watch this because it's a documentary about surfers, but I think you would enjoy it if you watched it.
