If you're a big enough fan of Paul McCartney's to get past the fact that there's not too much to the plot, I would recommend for you to see it. The music is fantastic (he even kept the classics such as Eleanor Rigby, Here, There, And Everywhere, and The Long and Winding Road) and it's also just a fun little movie to watch if you're in a good mood. It's certainly not the greatest thing our Paul has ever done, but it not the worst either (Yeah, remember the Magical Mystery Tour same story: good music, bad plot). I give it a 7/10.
