As a fan of the Foo Fighters and almost any movie to do with rock music, I highly enjoyed this documentary that chronicles the band's career, inner turmoil, and absolute dedication to their craft. Back and Forth not only captures the history of the band, it also traces the production of their latest release, Wasting Light.
I would definitely suggest this as a quality rental. Personally, I'll end up buying it. I can watch movies like this over and over again.
