Star Wars. The original trilogy of course. While the prequels are still pretty good. The Phantom Menace was the first film I ever saw at the cinema, so I don't really hate it so much, but I don't like some aspects of it.
Anyway, out of the originals, my favourite is The Empire Strikes Back, because I like the battle at the end, and it's got a really engaging story. Also, it doesn't really cover the battle between the Rebels and the Empire, just Luke Skywalker's training with Yoda, and Han, Chewbacca, Leia, and C3PO trying to avoid Darth Vader and rendevouing with the other Rebels.
