From The Bleacher Bum:
The Break-Up has serious star quality with Vince Vaughan, Jennifer Aniston, Joey Lauren Adams, John Favreau, Vincent D’Onofrio, and five other easily recognizable faces, and all gave solid performances. Vaughan and Favreau made me laugh out loud several times. Aniston and Adams were smart, lovable, entertaining and looked good. However, the movie is hampered by the script and the director. Scenes which were supposed to be funny were serious, and ones that were supposed to be serious were funny. It lost its way very quickly, and the actors were left with very little to work with. This movie is a date movie that is not enjoyable for two people on a date.
