Just saw it this afternoon. Yay for matinees.

3D was okay. There were some places where it was really good, and I was more impressed with it than I have been at other movies. (Also, I've watched most 3D movies in the same theater, so I wonder if that's part of my problem.) But I think it would've been enjoyable even without the 3D.

(Speaking of 3D, the previews were really good in it, but I fear that the movies will be mediocre anyway. Oh well)

Overall, it was a fun movie. Like car chases and explosions? Then this will do it for you. And it did indeed have some things in it that differ from the typical hero movie. But yeah, it was fun. Worth watching. Nothing revolutionary, but that's okay.
