This flick's story is pretty mediocre, and for the most part, the special effects aren't all that. There is some charm to this film, though (and as I've now seen it three times, I'm seeing it more). It doesn't make up for the generic plot or atrocious ending, but some of the key performances in the film add just enough zest to allow the movie to not end up a complete failure.
What did you think about this science-fiction/horror hybrid?
