Watched this yesterday on the web. It sucks big time. Don't pay to see this trash.
First off there is no character development....so you don't really care what happens to any of them to begin with. Second, half the movie takes place in the dark, so you can't see what's going on. Great way to save money on actual filming I guess. And finally the music sucks as well.
If you've never seen the original Red Dawn, rent that one instead.
