I saw TPM in theaters probably six times. While I didn't like Jar Jar, and wished the film WASN'T a kid's adventure story, it was a fun kid's adventure and I liked it and the love of "Star Wars" kept me from worrying about many of it's basic storytelling flaws.
I saw AOTC once. Just never really had the impulse to see it again. I didn't think I HATED it right away, but the fact it failed as a love story and a mystery (both things I would have dug if it had succeeded) never sat right with me. If you had asked me I would have said it was a good flick, but perhaps that was just denial. Got the VHS for Christmas and watched it once or twice, but never really gave it much thought.
I still stand that ROTS was a pretty good flick, and had it been anything other than the climax to the greatest saga of film history, I think I would say it was damn good.
It was only after they all came out and some time passed that I got the general feeling of "that was extremely underwhelming."
It was when I first saw "The Phantom Edit" and for the first time really dug TPM as a movie, not just as"more Star Wars" that I started to see the major flaws in the stories that had kept me from really loving those movies.
