I saw it last night, and I thought it was great, like so many others said. I would say it was most definitely better than the first.
So, I guess it's Green Goblin II/Hobgoblin next time, unfortunately. I didn't really dig the Goblin too much, and I don't really want to see him again...I'd rather it be the Lizard, since they kind of set it up for him, too. And Man-Wolf, come to think of it.
I'm still debating on whether they should bring in Venom/Carnage or not. I'd love to see it, don't get me wrong, but well... I don't believe they will.
It would be cool to go along with what Shallown said, though, if they would show Spiderman beating up on some of the peon villains rather than thugs. You know, the really more-or-less worthless guys like Electro and Rhino and Scorpion and the dreaded Walrus.
What was the other name the guy suggested for Dr. Octopus? There were three: Dr. Octopus, Dr. Strange (

), and something else.
I did like how they did the little Dr. Strange joke as it's kind of giving you the idea that there's more super guys out there than just Spidey and whoever his enemy is for that movie. Even if they don't focus on the other villains/heroes, I'd like some indication that they're around.
