First off if you don't like alien themed movies, or anything supernatural don't bother. NOW for those of us who enjoy creepy, alien, supernatural freaky stuff. THIS MOVIE WAS VERY WELL PUT TOGETHER, started at a nice pace and kept me interested all the way through. whether you believe in the subject matter or not it was fun, it was creepy, very good acting. sent chills through my body a couple times, movies generally don't do that !
