It's touchy for me, being on the SM board. Personally, I'm more of a Batman fanboy, but I do like comics and comic films in general so I'll give this a shot:
Spider-Man 3, for me, was like riding a monster roller coaster after a huge meal. I enjoyed myself thoroughly during the ride, despite the few bumps along the way that made me hurl a bit, and I ultimately walked away from it feeling empty and akward.
It was the same thing after seeing X3. It's more obvious pinpointing the reason behind that (Ratner's directing style in comparison to Singer's) but I can't say that for Spidey 3. Perhaps it's because this is the first installment where Raimi himself took a stab at the writing. I'm not sure.
There's just something about it that feels...off. I can see the transition from SM1 to SM2, but not from SM2 to SM3. I can pair up SM1 and SM2, but SM3 is it's own thing that I really have a difficult time acknowledging in the overall terms of the franchise. I guess it's just because it's not where I personally would've wanted the story to go. I'm sure EVERYONE here has their own take on that.
Part of it is Venom, but not because he wasn't welcome; Venom is one of my favorite Marvel villains. But as reviewers have said before, and if you know the story behind Arad's pushing Venom onto Raimi, you can most definately feel Raimi's tolerance towards Brock as a character.
In another opinion, since that was the case, Raimi and Arad should've come to this compromise:
SM3 should've only delt with continuing Harry's arc and the Sandman. This way, Raimi and Co. would've given us a classic Lee/Ditko trilogy. Then, towards film's end introduce the presence of the symbiote, setting up a darker trilogy more in homage to Todd McFarlane and the works of the late 80s/90s with rogues like Venom, Lizard, Shocker and Chameleon.
And had it gone that way, Raimi, whose love for the original Lee/Ditko books is imminent, could've decided not to continue and Columbia and Marvel could've potentially brought on, with enough searching, a new director whose as much a fan of the 80s and 90s Spiderman as Raimi is of the original 60s Spiderman.
Unfortunately, that's not gonna happen with the hasty inclusion of Venom in SM3 which, coupled with the inclusion of the Stacys, are the two factors I feel should've been merely hinted at, if not ultimately left out of the final product.
I give Spiderman a 5/10...I'm really on the fence about it. I mean, I want to like it as much as the first two, but I honestly can't, which truthfully really disappoints me. Though to be brutally honest, I'll only shed tears if this happens to Batman...AGAIN...
Bottom Line...like the rumored X4; make Spidey 4 and make it better. I don't know how long it'll take or what it takes, but do another one. If not to just go out on a high note altogether (trying to stay PC with the SM3 appreciators) I think everyone would agree they could go out on a note higher than SM3.
