Holy Crap was this bad
Obviously, the dialogue is beyond boorish and the acting is disappointing...(looking at you Gary).
It also laced a dark and ominous tone (both visually and acoustically) that would have enhanced the fear and creepiness factor.
Perhaps if they'd gone in a direction of more realism, like not using lip stick on the women, everyone 'freshly bathed' and hair styled, nails manicured, and teeth whitened it would have been better.
If it had more of a 'The Name of the Rose' feel to it, then it might have actually worked.
