MTV has the latest, best trailer yet for 'Mirrors'. First trailers were a bit hokey and watered down with the feel of a techno version of 'The Shining' without much foundation. Next version(s) went to the other extreme with very graphic depictions -- they were better but a bit crude and off putting. New version finds a happy median, implying more graphic elements but cutting away before the gore hits the fan, making for a much more effective trailer with broader appeal.
MTV also has what I believe is the first hi-def trailer. There's something about the simple fact that the image is bigger (and more clear) that makes the sequences creepier -- should be a scream on the big screen. Check it out.
