I liked the movie and I watched it twice within a week. I don't like Page, I don't like The Edge, but I am a big Jack White fan.
The movie isn't an eye opener in any way, but just interesting and fun. I love the small things like this:
The Edge and White looking like a kid getting a new toy and totally in awe when Page plays Whola Lotta Love.
Jack White teaching Edge and Page to play Seven Nation Army. At one point White says to turn of the octavers and Page and Edge both jump to their pedal boards. Just funny:)
Old demo tapes of U2, The Edge asking Page about Kashmir and Page teaching them to play it. A lot of old footage...
Just three guitar players having a lot of fun together...
I imagined what would be the best line up for "It Might Get Low". McCartney, Flea and Tal Wilkenfeld?
