I'm not going to mention a plot line that was so thin as to be non-existent (lunatic breaks out of mental institution to go home for Christmas), directing and acting that was just "posted in for the pay check" or the fact that none of the main characters were all that likable. I will say that the film was little more than a rehash of a bunch of ideas that had been thoroughly "warmed through" in the 1970s. Trust me when I say that the $7 you might have spent would be better spent on almost anything (and I mean anything) else.
The only good thing about the movie is that they person you expect to live till the end (Michelle Tractenberg off the Buffy tv show) fails to make it. Even that plot point is becoming, however, a bit over used.
