Saw it yesterday (only person in the theater). It was OK, not great at all but entertaining. I love the Andrew Garfield Spidey and his attitude, also thought Emma Stone as Gwen was quite good. I did think the storyline was too 'busy'. I mean, three villains, Oscorp, personal quests, Gwen, her dad, aunt May...yeah, I know that he's got a complicated life and that's the gist of the movie...but it was just a lot to take in. Also, I literally chuckled at Paul Giamatti as Rhino. Just WAY over the top. Overall, the villains were juts pretty shallow, predictable and 'meh'. Winter Soldier was A LOT better IMHO.
As an aside, I'm a huge admirer of Saving Mr. Banks, so every time I saw Paul Giamatti I wondered what the heck Mrs. Travers did to her chauffeur to him off so much. Also, good to see BJ Novack/Bob Sherman in a role; but when I saw him I thought "Hey, it's Bob Sherman, maybe he'll sing...where's his brother?".
