Watched the original X-Men movie last night after not having seen it in like 5 years. It's definitely great. And the first 6 minutes or so of X2 might be the best thing that's ever been put on film, ever. The rest of that movie was fantastic too.
X3 sucked. I actually thought Kelsey Grammar made a good Beast, and I honestly thought the Juggernaut turned out really funny. Even his "I'm the Juggernaut, *****!" line made me laugh in the theater. The movie as a whole was still nowhere near the quality of the first two. Unfortunately, Bryan Singer didn't use the same quality of the first two films for the Superman movie that he left X3 to direct. So in the end, we all lost.
I'm skeptical about Wolverine. Of course the trailer makes it looks like your typical action movie, because that's what a trailer is supposed to do. It could actually turn out being good. Then again, it's Fox, so it's much more likely that it'll suck.
I wish they'd give the X-Men and Spider Man back to Marvel, and let Marvel make the movies. I know they've only done two movies under their own flag, but Marvel hasn't missed yet. Say what you want about the Hulk, but I thought it was great. Not as in "It was better than the other Hulk movie, so I guess it was okay?" I mean I genuinely thought it was great.
