I watched the DVD with my brother a few nights ago.
I really liked how regular and unassuming The Edge was. He seems like a guy you could have a beer with. I was very impressed by his playing and how he's embraced technology for his creativity.
I'll admit I was pretty disappointed by Jack White. I guess the movie reinforced that I like his music but I don't like him. He comes across as arrogant, self-absorbed and pretentious. When he says things like how he "never" wanted to play guitar, and how he always wants playing guitar to be a struggle, he pretty much lost me there. I guess that's a punk aesthetic talking, which is fine. He could learn a lot from Page and Edge, I think. They show a real love for their instruments, whereas White shows literally the opposite. His approach works for him, but I don't think anyone should think playing guitar should be like wrestling an alligator.
The parts following Page around were fascinating. The segment at Headley Grange had me drooling. To be at that place would be to visit a rock and roll cathedral.
