We went to see this movie tonight. If the showing we were at was representative, it will make a lot of money this weekend.
Overall, it was a good flick. I'm an SF fan, so last-man-on-earth movies are nothing new to me. But, hey, it's got Will Smith, so it ought to be good, right? My wife was terrified at some of the scenes, she nearly came out of her seat. My sister (who hasn't seen it - we talked after the movie) said she thought it was a horror movie. In some ways, it was. But the horror was reasonable horror (what an oxymoron!)
What surprised me the most was the religious references. They were done in good taste, if a little bit hurried and pushed. Even Smith's character declaring there is no God made sense. And religious folks will be glad the way it was all handled.
Overall, a good movie. Made for the big screen, with surround sound and all (there was glass falling behind us in one scene - neat). Spend the $9 (or less for a matinee), don't wait for the DVD. And warn your wife that it could be a little bit bloody and jumpy.
