I thought this movie was quite a good sci-fi flick. I'm biased because I like Chicago and Will Smith and am a Trekkie in withdrawl (from the series). You guess who the villan is at the beginning but you are still drawn into it. There is a somewhat startling revelation about three-fourths of the way through which you think "Why didn't I get that before!?!" This is a fun action flick and get lots of popcorn, it's worth it.
