Query: An empty Sci-Fi thriller

This is one of those movies where you're just waiting for something to happen but never does. It just meanders along and relies on its special fx, which are quite good, to give the movie any substance at all. A couple of good performances by the cast without being outstanding, but there was only so much they could do with a shallow script. They look lost and wanting to give more but are restricted. There are better, a lot better sci-fi movies out there than this one. Special features aren't very interesting either.
