I saw it and its amazing. There are countless references to not only Beatles songs but songs form other music greats as well as major roll players form the 60s peace movement. If you like the Beatles or just music you should see this film. This is a musical, which I'll bet is not everyones thing here but it shines through as being a bold, unique, trippy, and completely original film. I loved it and I highly suggest this to everyone.
