1 - my favorite. i liked everything xcept green goblin's costume.
2 - a really great continuation of the story. Doc Ock's look, origin and confrontations with Spidey were better than Goblin's. The threat to the city bigger. Confessing to Aunt May, struggling with his choice to be Spiderman/losing powers, MJ choosing Peter - good stuff that makes me overlook the crap like his unmasking on the train.
3 - fun, but by far the weakest of the three. Sandman was a complete waste, He seemed to me far more tacked on and less important to the overall story than Venom was. They tried to make him more than just a 2 dimensional excuse for cgi wonderment with the daughter & uncle Ben stuff and failed, only ending up with a muddy to non-existent character arc. They should've cut him out and given the screen time to black suit origins, Pete's inner struggle & romance with Gwen and of course Brock/Venom. Should've tied the symbiote origin into JJ's astronaut son's trip to space instead of the lame meteorite landing right in front of Peter. Pete storing the hostile symbiote in his trunk made no sense. They get a second chance to design a BA Goblin costume and this Xtreme skyboarding, sword wielding thing is what they come up with? Instead of MJ in a thin dress in the rain or wind we get not 1 but 2 crappy songs. Ugh, and the butler speech, those crappy newscasters and the "wicked cool" kid?! Still, the action was good esp the first fight, it was very funny, and great to see the black suit stuff on the screen.
