Star Wars is something I've always been able to take or leave, even the original trilogy. I thought the original trilogy was good overall, but mostly due to the efforts of the first two movies as the Ewoks just took me out of Return of the Jedi. I mean...if you ever wanted to make the Empire look like a complete bunch of pussies, it's hard to imagine a better way than by having them beaten by a race of midget bears with stone age technology.
As for the prequels, I don't think they're as bad as some try to make them out to be but I wouldn't call them good either. To be fair, however, I admit that I'm generally not a fan of prequels. I mean, I already knew that Anakin Skywalker became Darth Vader, I knew he betrayed the Jedi Order, I knew there was a war in which the Old Republic was essentially remade into the Galactic Empire so I didn't need to see three movies in which all the little details were added because, to me, they weren't all that interesting in the first place. That's not to say they couldn't have been interesting, it would've done them a world of good had Hayden Christiansen's portrayal of Skywalker not made him come off as this whiny little emo bitch that you just wanted to kick right in the teeth every time he opened his mouth. I did really enjoy Ian McDiarmid's over the top, almost satanic portrayal of Palpatine, I thought he was the highlight of Revenge of the Sith.
