Murder Mystery is about a whiny cop who keeps lying to his overly tolerant wife. For the first third of the movie, this is an annoying couple going on vacation, and since it's called Murder Mystery I kept just hoping someone would die.

A third of the way in the bodies start piling up and the movie becomes genuinely entertaining, as the couple bickers and investigates as the police make them prime suspects.

The movie is amusing, laugh-out-loud jokes are rare but do happen, the plot is fast-paced, the mystery is nonsensical but not terrible, the movie gets progressively better as it moves forward, and Sandler and Aniston have the persuasive chemistry of a couple that still care even if they are often frustrated.

If you cut out the first hour I would easily give this movie a 7.

Full disclosure: I love murder-mystery comedies, even the lesser ones. So even though the movie has its faults, I would recommend it to someone with the same inclinations.
