I have to say that, but the acting on the two first movies, in my opinion at least, was pretty decent, Maguire puled off an at least decent spider man. You know, an scene I will remember forever is that one were spider man saves the train on the second movie, but I talking about the scene after he pass out, and everyone sees his face and are shocked and amazed of how spider man is just and teenager guy and promisse to him to keep his secret, it was really memorable.
First movies acting was okay, if not spectacular, but I maintain that the second movie had acting so wooden they may as well have replaced Maguire and Dunst with a couple of redwoods.
I thought the train sequence was particularly cheesy. Granted, this is in a movie trilogy that I suspect Kraft had a hand in, but that one just took the cheesecake. I respect that you liked the scene, but personally I thought it was very campy. I'm not sure there was really any good reason to have Spider-Man unmasked in front of an entire train full of people other than a sentimental moment that I'm not particularly sure really served the plot any.
To be fair, though, all this was to be expected when Sam Raimi came on board; much as I love the Evil Dead films, camp really doesn't have a place in movies like this, but the guy came from a B-Movie background, so it wasn't entirely unexpected. The entire trilogy has moments like this. Even the first one, which I actually liked. I mean, it's great to see that Goldar's doing well post Power Rangers, but a green recolor job does not a Green Goblin make.
Three... man I just don't even know what the hell happened to three. A lot of people try and claim the inclusion of Venom is what brought the movie down, but I don't think for a second that removing Venom from the last act of the film would have saved it. Man that movie had problems.
To not be completely negative, however, I will say that Spider-Man 2 had some of the fundamentals down. There was the basic understanding that a lot of what makes a given Spider-Man story appealing is the superheroics mixed with personal drama. Obviously, this doesn't often go quite far with the romantic entanglements in the movies - since, you know, they were insistant that Mary Jane was the only viable choice - but they still nailed that in other ways. Regardless, that's the main thing they got right; in quite a few other respects, they didn't exactly get the character of Peter Parker.
I recently played Spider-Man: Shattered Dimensions and while the personal drama is mostly absent, the game presented a much better Amazing Spider-Man in tone, jokes, demeanor and voice acting.
But I'm not saying you're not entitled to like 2.
