Excellent photography, disturbing psycopath, but highly implausible, IMO, that the husband would not go to the police, after beating the shit out of the man he suspects of murdering his wife.
Instead, he goes along for the ride with this clearly disturbed and evil man....what the heck did he expect would happen?
Well acted, well shot, disturbing but improbable, and this is where the whole film collapses.
