4/5
The Other Woman is a surprisingly stellar film, funny and emotional in just the right concentrations. The plot follows Carly (Diaz) as a high-powered lawyer who discovers that the man she's dating, Mark (Coster-Waldau), has both a wife (Mann) and a second mistress (Upton). The initial premise sounds bland and cliché at first--and little more than a substandard chick flick--but it surprises time and time again. The writing is extremely well-done (e.g., "cry on the inside like a winner") and the characters feel much more fleshed out than those occupying your standard rom-com. Diaz is truly outstanding. I am not a fan of Cameron Diaz in general, but this is honestly one of my favorites roles from her entire career.
The Other Woman has a couple of flaws. First, it is filled with unusual, sometimes uncomfortable, music choices. Second, Mark's final comeuppance (despite how much we have all grown to hate him) is excessively over-the-top, indulging in way too much schadenfreude for comfort. But for all it gets wrong, it gets the most important things right. The Other Woman is a comedy with heart and strong characters that make you a little better off after watching it. And isn't that what movies are all about?
