Not even the Rock can save this picture based solely on it's plot. It'd be like asking Jamie Foxx, Robert DeNiro, Al Pacino, Meryl Streep, Glenn Close, Tom Hanks, Paul Newman and Jack Nicholson (basically some of the best actors ever) to star in Scary Movie 6 and guarantee that it'll be a good movie. If a movie has a shit premise, it's going to be a shit movie, IMO.
