So I watched It Might Get Loud the other day. The title may well be the best thing about the film. It is supposed to be a history of the electric guitar told by three rock guitarist of different generations. Perhaps it succeeded on this front, but not really in my eyes.
Even if it did, it could have been so much more. There can be conflict in a documentary and there can be expression; only don't look for them in this film. I felt they asked Jimi Page, The Edge, and Jack White to 'interview' each other, rather than have someone with a storytelling agenda press forward with certain issues. It's not exactly as if any of the three are journalist...
The best underused content to me was Page saying--out loud-- "Pop music is rubbish," and then all parties involved let a comment like that die... even the lead guitarist from a 'pop band' like U2.
It could have been so much more.
