I'm a Starwars fan and can't really see why others give it such a conservative vote- it's substantially better than the last 2, and gleefully it never really stops from start to finish - it's quite the roller coaster.
Granted some links to entwine the saga are a bit superficial but frankly, at 2h20 it's plenty long enough, and at the end of the day it's Star Wars, not the Godfather.
