thats why im thinking if they do something like that, and do it as a 3 hour (maybe a 3+ hour) movie it could easily be made to work. Raimi has done a good job so far though, so i think he would be able to affectively pull it off. I mean, we have spider-man's character pretty much set up. Green Goblin 2 is set up. Lizard wouldnt take that much cause conner has at least been introduced. Venom could probably be done fairly easily, but eve so that still leaves 3 more guys to set up. my major concern about that would be that there wouldnt be enough time to set all that up and still have a good 'fight/struggle' between spidey and the villians.
honestly, i think its gonna go the 2 villian route with a movie running about 2.5 hours. If Raimi sticks true to the first two it will turn out fine. we might not get to see the villians we want, but what we do see shouldnt dissapoint...just my opinion.
