What did I like about The Phantom Menace? Ugh...Darth Maul? I guess? He's a character that could have been around for all three movies, but they killed him off. I actually enjoyed the Trade Federation villains. Cool looking characters, but those accents?
Attack of the Clones is a movie that didn't learn any mistakes from it's predecessor, but it had some interesting things. I enjoyed the Obi Wan/Jango sub-plot and the Geonosis Battle is pretty fun. Other than that? Meh. Again - why did they kill Maul? Christopher Lee was a great/fantastic actor, but he was wasted in the role of Dooku, and that could have easily been Maul's spot.
I've always considered Revenge of the Sith to be a pretty great movie. Despite some issues with dialogue ("Hold me like you did on the lake at Naboo" and "NOOOOOO!") and the Obi Wan/Anakin basically becoming a '90s' WWE Hardcore match'. I don't have many qualms with it. That Order 66 scene is
.
EDIT - I tried ranking the movies, but I kept going back and forth (another reason why I rarely rank series movies) so let's just say Empire is my favorite, Sith would be in my top 4, and the only ones I don't really care for are TLJ and TPM with AOTC going back and forth.
