I'm soo mad

So the other day I was thinking about the whole Richard Ramirez thing, being that when I was little my family had some friends down in LA about a block or two where Ramirez killed that couple, I remember seeing road blocks and patrol cars everywhere.
So it prompted me to rent this movie, although watching only 15 minutes into it, I realized that I had already seen it before, but I don't ever remember watching it, im so mad.
