Okay, first off, before I say my commentary on this, let me just say that I'm probably one of the few here who hasn't seen DMC yet.
I didn't like 1st the first time around seeing it, thought it was pretty stupid, but on the second viewing, so I could remember what happened before I saw DMC, I liked it more the 2nd time around, but still, I had my problems with it. Hopefully, it doesn't have the same problems, the trilogy of POTC, as The Matrix sequels did, but everything points to that it does. I've been through many websites and through some of my friends who've seen it, and majority say, most of them do agree a 2nd viewing of DMC is almost required cause there's so much stuff going on, it's hard to take in the first time. That, and many really liked or loved the second, or they didn't like the second that much, and thought it wrecked it, like majority of the critics said with DMC. Not having seen DMC yet, obviously, can't make my opinon yet.
Spider-Man 3, DEFINITELY, I personally think, will be the crowning jewel of May 2007. It's bigger, better, and it's the sequel to one of the greatest and biggest endings that an action movie had. Spider-Man 3, from what I've heard, could take the cake, cause there's something for every age, and this one, as I've been hearing, *might* be the last of all of them, since it was designed to be a trilogy. There's 4 villains in this one, awesome new effects, more complexity, drama, and character relationships are about to get more complicated as seen in the trailer, as Mary Jane and Harry actually makes moves on each other!!

PLUS, the fact of everyone asking WHY does Spider-Man have a black suit on will keep people coming back for more. I think Spider-Man WILL definitely get to be a HUGE money-maker, and being the end of the trilogy, more stuff involved, that'll attract people. That, and Spider-Man has got to be the BEST in superhero movie-wise, best sequels, originality, and it's complexity is untouched; only Batman Begins and Superman Returns can go along with that title.
