From the commercials, this movie looked like it might have potential. Then I went to see it. Wow. Try using a plot formula that has been done about five hundred times already in B horror movies. Put it in space, because the kids are really starting to like science fiction. Get some decent actors who need work to pay the bills. Use really unique horror devices, like phantom kids running around on a space ship, (Is the lead female character so blatantly stupid that she can't remember she's on a spaceship and she didn't bring along the kids?), Sam Neil in one scene holding his eyeballs in his hands and in a later scene they're back in his head.(Must have a really spiffy demon surgeon onboard.) This movie, to put it bluntly, just stunk, should never have been made and I should have been paid to watch this crap.
