The idea is muddled and the dialog is frequently too clever... Also, all of the characters have secrets which are to be revealed at the most dramatic moments--frequently by the characters spending a lot of time talking when the situation is desperate and seconds are supposed to be critical. Furthermore the monsters are not terribly convincing and are shown enough that they lose any sense of uncanny menace that might have been there when they are first glimpsed.
Do not expect the story to make sense on any level and you might be able to enjoy the film anyway as it is technically decent and the actors are not bad.
