"Murder Mystery" in a way is a parody mix of Agatha Christie and Inspector Clouseau. Most of the film's humor comes from just how out-of-place Aniston and Sandler are in the world of high society. That being said, J. Aniston pretty much owns this movie. Nevertheless, it look as her like rest of the actors didn't really enjoying the experience. At the end, "Murder Mystery" is a likable, lightweight comedy, at times cheap and dumb, occasionally amusing and rather innocent as an airplane 'watch and forget' movie.

Rating: 6, just because of Jennifer Aniston.
