Just saw it and must say I thought it was pretty good. I didn't have near as much issue with the pacing or flashbacks as it appears many of you did.
The most important thing they did for me in this film was make a Superman/Clark Kent that I could actually like. I really can't stand the character in any incarnation, be it the comics or cartoons; but I REALLY liked this one. I think that might have had everything to do with Cavill, though. That dude is just a stud. I felt like I really felt his emotion in the intense scenes
.
I don't really feel like typing much more at the moment but I thought pretty much every character was well-acted, particularly Jor-El and Zod. The action scenes were top-notch also. I'd definitely recommend the movie.
