As someone who was looking forward to The Phantom Menace in 1999, y'all need to learn to manage your expectations.
Actually, let me give you a tip. This actually worked for me, and I ended up enjoying TPM a lot more than my friends did. I went completely spoiler free - no watching trailers, no reading preview articles, no reading interviews with the cast, no browsing internet forums. I knew absolutely nothing about the movie except:
I unfortunately saw these two on a magazine cover holding light sabers, so that information leaked. I didn't even know that Ewan MacGregor was playing Obi Wan (I suspected one of them was, as I assumed Obi Wan would be in the movie).
Anyway, I saw Darth Maul for the first time when he showed up on screen. "Wow, that guy is bad ass," I thought. I saw his double-bladed light saber for the first time in the final fight scene, and it blew my fucking mind. That fight scene was the best thing about the movie, to be honest. I honestly didn't know Padme the handmaiden and Queen Amidala were the same person until the reveal in front of the Big Nass guy, or whatever his name was.
I think it makes movies much more enjoyable to go in completely spoiler free. My best example is Prometheus, which I had no idea was a supposed to be a prequel to Alien until the very end (it's been years since I last watched Alien, so I didn't recognize some of the obvious signs). I didn't know anything about that movie going in - as far as I knew, it could have been a movie about the Olympian creation story.
Anyway, I have no idea what's going to be in the new Star Wars movie. I have no idea who is in the cast. And I'll keep it that way until opening day (or whenever I end up seeing it). Even if it turns out to be a crap-fest, I'll still have the magic of seeing it all for the first time in its proper setting.
