The message was as subtle as being slapped in the face with a fish, and wedged in the mouth of the fish was a sledgehammer, and on the sledgehammer was written in permanent marker "ALL MEN ARE SCUM!".
I really did like the premise, and the first 1/3 of the film was somewhat enjoyable, but it just went too far (refer to opening remark) and became very tedious, boring and utterly ridiculous.
Perhaps the worst horror / thriller film I watched that year.
