Terrible. Garbage. Nonsense.
The trailer for this movie is deceitful. It leads you to think the movie is a thriller, and the premise looks great: abused wife asks ex to kill current husband by tossing him in the ocean for the sharks. What you get is a tangled mess of absolute nonsense. 3% thriller. 97% shite.
Headed by two Oscar winners, you would think this movie would be a winner. What were they thinking signing up for a movie like this? They must have been paid a lot of money.
Do not watch this movie. Or watch it just to see how bad it is.
