Watched this last night and I thought it was great, especially when comparing to many other skateboard/skateboarder documentaries.
I think there are many things it did right, like focusing on the skateboarding, e.g. in the second half there could've been spent on focusing on his superstardom where Hollywood whatshisnames praise his talent and influence, but instead the doc focused on Tony's personal shortcomings, his drive for skateboarding and his peers. Maybe the last half could've have had more on how his emotional issues affected his life and relationships, but then again the whole documentary was about that, so I don't think it was necessary.
All the talking heads were great, especially Lance and Neil. The soundtrack was fitting and all the archival footage was awesome (of course if you know skate history, you'll have seen most of it before).
The documentary shows how brutal beatings Tony has endured and tries to shine light why he (and many of his peers) continue to do what he does, despite the fact it really is "stupid" and unfathomable to any non-skateboarder. But I think any skateboarder can relate to it and know how it's unique compared to pretty much any other sport/hobby.
In Tony's case, it's really interesting as he has already achieved everything: fame, money and respect of peers. But he's still out there trying to push his and skateboarding's limits when he could've just stood back and reap the fruits of his labor and live comfortably.
