Uno, dos, tres.
One was really fantastic. The origin story makes re-watching a little rough at times. My philosophy is this: I want to see SPIDER-MAN, not Peter Parker or Mary Jane.... Give me as much Spidey as possible.
Two was very well done. The depiction of Doc Oc could have been better had they not tried to turn him into some sympathetic character. Let a bad guy be a bad guy.
Three.... oh man. I did enjoy the Sandman stuff quite a bit. Venom felt forced, and he was. Really, if the studio wanted Venom in the film then GIVE US VENOM, not Topher Grace with a Venom body. Song and dance number pushed this one over the top as the true rotten tomato of the group. Still worth watching from time to time.
