I adore Revenge of the Sith, both ironically and unironically. It's supremely entertaining, and it's the Star Wars film that feels the most like a grand Shakespearean play.
Also the film is a meme generator, every other line of dialogue just cracks me up. Ian Mcdiarmid hams it up to awesome levels.
I can definitely get on board with this but I really didn't care for it at all when I first saw it. It's grown on me....
