I hated the first one. Green Goblin looked terrible. I will say that the Doc Ock looks a lot better in this one.
As for the Carnage / Venom question. Anyone should know that there is no way either one can appear , without them butchering the story. It is way too long and complicated, espically Carnage... Not to mention Sam Rami has said he does not see why people enjoy either character and has no intentions of ever briinging them to the screen... Then again, he has also showed signs and commented about not comin\' back for Spider-Man 3. Which means, another director may very well bring them into the storyline , but if so, it will be butchered. Just like Bane\'s character was butchered in Batman & Robin.
