Just watched the 3D blu-ray last night. Gosh damn the 3D is awesome. I saw it that way in the theater as well but Spidey flying around and Electro's lightning blasts look beyond amazing.
Anyway, I wondered if my initial buzz would be greatly dampened by a second viewing and it wasn't. I still thoroughly enjoyed it. In fact I actually had TKDR in the player first but after sitting through 15 minutes of mayor/Gordon speeches and Wayne shooting arrows at Kyle I just **** it and put in ASM2. MUCH more enjoyable. I even paid attention to what I remember to be major criticisms against the film like "there's too much going on, it's too bloated, etc.," and I just didn't feel that. The wide array of villains and Gwen/Harry/Aunt May/Max/Parents problems to me just conveyed the chaotic life that Peter tried to manage. I always picture Spidey as having too much on his plate and this movie really made that clear. Now if you didn't care about certain plotlines I can see how it'd be annoying but I liked them all.
And that ending still just rules. It'll be interesting to see how my second viewing of DOFP goes but I think I might prefer ASM2 over it. We'll see.
