Why not get both? But if that's out of the question, I'd suggest the second one. Not only does it look cool, but it captures the feel of the movie perfectly. I like it so much, I have it set as my wallpaper on this computer.
I'm not trying to derail this post, but personally I'd have go with the Doc Ock poster. I believe it was the first poster they publicly released for the movie and in my opinion, it's still the best one.
#1 definately. I've never liked poster #2, mainly because something about Parker's body just looks weird in that picture, like the head is too small for the body or something. Maybe it's just the angle, but I just think it's an awkward poster.
I like that the posters (and the movie) show the charcters in action in the daylight, as opposed to every other superhero movie, which takes place exclusively in the dead of night.
I have one of the Advance posters, in which you see Doc Oc reflected in Spidey's eye. It looks cool next to my advance poster from the first movie, in which the WTC is reflected in Spidey's eye.
#2 I have it set as my wallpaper too. And I added inset photo of Spidey near the end of the movie when he is crawling on one of his webs and the costume is torn.
I'm a fan of subtlety when it comes to SuperHero Movie Posters. My vote is for #2, hands down!
(I'm not a big fan of the Spider Posters for the first film, and I loathe the DVD cover art that came out for both the widescreen & fullscreen versions of the film).
By the way, where are you ordering the posters, and for how much?
