I really liked Dredd
--just saw it yesterday (had some free time to kill so I went to see it on an impulse). It was just a really cool action flick. Really nailed the dystopian future thing well, IMO, and had a villian that I'll remember for some time.
To be totally honest, I don't remember seeing any commercials for the movie in my area. Heck, I didn't even know it had opened Friday until I checked my local movie theatre's website and saw that it was playing there (seeing it on a Monday afternoon before rush hour, there were only two others in the theatre with me).
