An interesting concept but the execution was dreadful. I am a fan but there were too many writing and directing mistakes.
The final scene in the lakewith the rubber knife actually had my wife and I laughing out loud - so much for suspense. It was obviously rubber and at one point it is actually flopping back and forth like a grade 12 drama prop. I have no idea how the director thought that this scene would be acceptable on anything except aSaturday Night Live skit.
The writing had too many short cuts that made the victims seem to be at fault. The friends in the first scene watch their firend be attacked and do not get the police and their motor boat to help? The jet ski girl's friends drive off without her and never notice she is missing? The mother leaves her son with the car when there is a killer on the loose? This is not the level of writing or production we have come to except from CM.
