It's Complicated

If you have a bigger problem with adultery than with the absurdity of your President receiving the Nobel Peace Prize while waging war in 3 countries, you obviously won't like this movie. If, however, you're into people: what their needs are, their feelings and what makes them tic, instead of religious dogmas that artificially make you feel better than your fellowmen, you might enjoy it as thoroughly as we did.
Granted, the movie has a few moments that come across as a little less than real or even right. For instance, you might catch yourself thinking, "Gee, I never thought I'd ever have to watch Steve Martin kissing Meryl Streep." But latest by the time they both light up a joint, you'll know why he was chosen for this role, and the laughs and brilliant "people moments" in the film will rapidly make up for any of its flaws.
For anyone who has ever been divorced and knows that these things indeed are complicated, this should be quite enjoyable, although the ultimate lesson to be gleaned from it may be nothing more than a reminder of the way Joni Mitchell once put it: "Don't it always seem to go that you don't know what you've got till it's gone?"
