We watched "It Might Get Loud" on Netflix streaming tonight, and it's a very easy movie to review - if you like rock 'n roll, this is the movie for you. If you don't, best head somewhere else.
It's a movie about guitar players - specifically, The Edge, Jack White, and Jimmy Page. Director Davis Guggenheim gives us a bit of backstory on all three, but the most effective parts of the film are when they just sit down together and talk, or even start to play a bit.
I'm not sure it's what you would call a classic documentary, but when the three sit down at the end, work out and then play The Band's "The Weight," such distinctions hardly matter. Any rock fan will find something to like in this one.
