Jacob's Ladder. A very odd, chilling movie that was different from my usual area, but definitely one of my favorites now...the shaking head shots, asylum scene, and demons were all very well done and chilling. The ending was the only thing I didn't like - when his dead son leads him up the stairs, into the light, I cried...but then it reveals something that changes the whole movie. I won't spoil it, because I hope this post inspires some people to check it out, but there were better ways to wrap it up.
Highly recommended.
