Interesting!
Behind the Mask started off a tad slow but it was good. You figured it out long before the characters did, but hey...that's movie life. I actually went to hear the music of my nephew who scored the movie as I usually don't attend slasher films, but overall it was pretty good. It was a different slasher flick and to me, was not the blood and gore that you see in so many.
Neat concept...the storyline. I would say GO see it. I generally am pretty hard on movies and don't go to too many of today's films. I had a personal interest here, but not so much so not to keep my objectivity.
