"Devil" - on DVD-Keeps You Guessing Thriller

I recently watched  Devil, PG-13, 1 hr, 21 min, out on DVD & Blu-ray, from producer M. Night Shyamalan. Five strangers are trapped in an elevator and discover that one of them is the Devil in disguise. Without giving away too much...A bad or evil aura in a certain space had opened the door to the Devil . He takes on a human form to torment people before taking their souls, enjoying the misery he creates and seeing the expressions on his victim's faces. Everyone on that elevator is on the Devil's  *#!* list and discovering what those reasons are is part of the thrill ride for the viewer. When the Devil is around, things don't behave normally and he creates doubt and confusion in your mind. Innocent people get caught in the crossfire and we know what happens to them. Big surprise twist at the end on who ends up being the Devil in disguise. One of the movie taglines is: "Bad things happen for a reason." Inquiring minds want to know if the Devil manifested the body of that particular person or did he take over the body and mind of an existing person. And without spoiling things, another mystery was the "bite marks"...why this just a method to torment? I wondered if the Devil had possessed her body with the marks as the point of entry. Interesting. This movie is one of three in a similar style produced by Shyamalan under the title The Night Chronicles. The second movie will be called  Reincarnate, slated to shoot in 2011. Other screenwriters and directors will collaborate to make his creative ideas come to life with these movies. Shyamalan has had several movies out in the last few years that did not live up to their hype, and that's not just my opinion. But Devil was a short, solid, character-driven, well-delivered movie that will keep you sitting on the edge of your couch!
