Query: Underground Christmas mayhem

Okay, parking garages are creepy enough so now I'm going to be too freaked out to ever park in one again. Or go in an elevator in the evening. Or ever trust parking lot attendants again. Or see security cameras without wondering who is watching at the other end.Great psychological thriller! I wasn't expecting a lot - low budget thriller with only two actors, for goodness sakes. But great, clear camera work. You can actually see what happens in the movie - they don't try to hide poor acting with low lighting.Rachel Nichols (even with the blatant boobarama display) was very credible as the victim who ended up kicking butt. And Wes Bentley - the best psycho since Hannibal Lector. If they gave awards for creepiness...AND the most over the top gross scene in a movie I have seen in, oh, forever.The pieces all held together and it definitely worked.......I'll have a blue, blue Christmas......
