I don’t have time to do a lengthy review on this right now, but I liked it. Dan and I saw it Friday night and then I took the kids the next day. (Side note: $10.25 for just me for the Friday night show, versus $12.50 for me and the 3 kids on Saturday at the Santa Paula theater).
Short summary: if you didn’t like many of the other recent comic movies, you probably won’t like this, but if you did you may. Has a lot of the same general audience feel as Spider-man 1, but probably without as much popular appeal (and a lot less marketing). The casting was actually very good (I was worried about a couple of them), with the possible exception of Dr. Doom. There were (as always) significant differences from the original stories, but none that wrecked the story.
