When I first saw the Phantom Menace I didn't hate it. I didn't like Jar Jar and the gungans but I thought it was alright. Even then I knew to seperate it from the Original Trilogy. I had a good time with Episode I as far as an "event" goes with the movie, hype, trailers, speculation, merchandise, etc. I knew it wasn't good, but I enjoyed that year from a "return to Star Wars" perspective. I was more interested in the behind the scenes stuff around that time anyway since I was getting into documentaries and films. I liked seeing the insight and concepts that went into making it. Overall I thought it was harmless, though I thought having a 9 year old kid be Anakin and a fully CGI, annoying, sidekick was a mistake.
Attack of the Clones did absolutely nothing for me. I remember liking that Darth Vader breathing teaser trailer and the "jedi shall not know anger" teaser poster. There was a sneak peek photo in Star Wars: Insider of what looked to be Obi-Wan suffering (I thought Anakin had a vision or something) and the inclusion of Boba Fett (didn't know that was Jango) and Christopher Lee intrigued me. I assumed it would be a more mature chapter. Once I saw a later trailer with Yoda wielding a lightsaber and C-3PO as a battle Droid, I was out. Hated the idea of it. I saw it once and it bored the hell out of me (other than the small tidbit of Obi-Wan being a detective) especially everything on Naboo. I didn't like it at all. I was more into the Spider-Man film and LOTR that year. Only thing I bought was a little Jango figure. I'll probably never watch AOTC in it's entirety ever again. It has the worst story and effects of all 8 movies.
Episode III was fun. The teaser and hype was great and I had a really exciting theater experience with it (got to go to a special screening a week and a half in advance with friends and I remember the screening was fantastic, especially the sound). I know people here rip the hell out of it, but at the time I didn't think it was awful. Loved Palpatine. Most of his scenes had me grinning from ear to ear. I liked seeing all the Jedi get slaughtered and I thought the clone troopers were really cool. There were little moments like Palpatine rescuing burn victim Anakin mirroring Ben rescuing Luke that really resonated with me for some reason. Collecting was fun again around that time too. I think it exceeded my expectations because they were really, really low. I don't like it as much as I did in 2005, but it was a fun movie. In fact, I was more excited for it than I was with Batman Begins believe it or not. My biggest disappointment was how much of a coward and mustache twirling villain Grievous turned out to be and now they handled Dooku, but the non-Palpatine villains were always problems in these prequels. It hasn't held up for me, but in 2005 I was satisfied with it and happy the saga was finally over . . . ugh.
I know the prequels are bad but I don't hate them. Never have. I used to make rants about how it didn't match up to the Original Trilogy and how none of the continuity made sense as well as how ****** the acting and wrtining in them are, but I enjoyed 1999-2005.
