Passing on the curse
So when one wears the suit, you become the demon. As in the case with the dog who ate the nose, or the piece of Kent's flesh within it, do you become the full demon despite not having the suit (skin). What if the mother had been bitten while fighting with the demon in the final scenes, would the curse for 5 children have transferred to her (sequel)? Is this curse akin to lycanthropy, in that anyone bitten, scratched but not killed by the demon, becomes the full demon? If so, what is the point of the skin suit? Is it just the curse's origination?
Thumbs up on the movie overall. Not perfect, but it did pretty well with a rather fundamentally silly premise.
