"Revenge of the Jedi" was changed because Jedi aren't supposed to seek revenge, so it would be kind of contradictory. There are some few rare posters floating about because the film's name was changed rather late in production.

I'm of the opinion that Attack of the Clones was the worst of the films. The Phantom Menace does have a lot of bad points, but I feel that most of them with the exception of Jar-Jar, are exacerbated in the sequel.
The new trilogy pretty much destroyed many of the things that people loved about the original films.
Seeing Darth Vader as an annoying kid is, well, annoying. But seeing him as an angsty teen is even worse, in my opinion. This is compounded with him being in some of the worst love scenes of any mainstream movie in decades and it's a formula for awful. I don't generally critisize acting, most of it, is at least tolerable, but some of it in the movie (Hayden Christensen in particular) is just quite bad with pretty bad writing to boot. If they didn't have constant special effects and often intrusive CG work, this would have killed the movies.
Most offensive to me though was the mystery, the mystique of the series, and what these films did to it. There is so much that you are left to wonder about and infer from the first series. But, the new trilogy again worked to destroy it. Trying to explain the Force gets most people annoyed, but to me what they did to Yoda was the worst. Ripping Boba Fett to little pieces (figuratively) by again, showing them as annoying children really was a turn off. But worst of all, I loved Yoda, the mysterious old sage, he talks about how it's not battle that makes someone great, and helps set Luke right. He's taken in the new series from that, the wise old teacher, to some hyperactive ninja muppet. It took away why from why he was supposedly great, and turned him into some gimmick. "Go see it for the Yoda fight".
That's why I feel that way, at least, what Phantom Menace started Attack of the Clones brought to it's horrible conclusion. Revenge of the Sith wasn't so bad, but it would have had to introduce Han Solo as an effeminate book worm to do worse than the others. Ewan McGregor really did seem to try though, his acting seemed the best out of the new series, and I did like Christopher Lee, but otherwise, they're just...sub-par movies.
