No I am not optimistic. Too many things I dislike outweigh what I do like at this point. Of course I will give the movie a fair shot but I would rather go in with no expectations than go in with a bar so high that I will be let down.
I have mentioned what I like on here...Emma as Gwen, Sheen as Ben, Lizard as the villain aside from his face and lizardfy plot, mechs (although I didn't mind organics), practical effects before I saw a ton of cgi, and Garfield as Peter.
Webb has to impress me. I am not taking a religious pilgrimage to his stoop to bow down to him just yet. I have said countless times in here...let's wait for the movie. It could be good, it could be bad. Who knows. If it's amazing I will be in here acting like a school girl. If it sucks I will have prepared accordingly.
