It is a sick movie, still I would give 4 star due to message it delivers. But many times I thought (may be others), that director is pushing things in your mind. You also got the feel that something is not right but then couple always turned back for stupid reasons, when any normal person could clearly figure out not to go back. His wife phone calling back the psycho couple is indigestible. So ending was pushy, but it could be different as well (never know). Again 4 star to promote the message it delivers.
