If we strip Star Wars of everything we know about Star Wars other than the film itself - we're left with a film about a guy and a large ape who moans weird
I never read the books, but I think the movies sometimes can get confusing when they don't go into great detail like they do in books. Like there will be a scene aand not a lot of explanation of why something or someone reacted the way they did.
Part 2 was excellent - especially the whole Snape Pensieve part.
I would really love to see more movies made with the backstories of Tom Riddle young and then go into Lupin, James, Sirius, Peter, and Snape in their early years as well.
