A movie with "aliens ate my mom and want to get me" plot. Mediocre acting matches well with below average plot. The idea is pretty simple: A bunch of humans are isolated while aliens run around and eat humans while in human bodies. That is, they eat humans after they turn from innocent humans to disgusting slime-dripping aliens. Make sense, right? I particularly liked the part when one alien kills another alien while trying to be a good human... just to confuse the person watching the movie -- the action makes absolutely no sense plot-wise. Enjoy wasting two perfectly good hours watching this movie on Sci-Fi channel.
