Friends with Kids is about choosing an alternative lifestyle while conforming with society. It doesn't work. The premise of the movie is a great idea, and the story has a funny drama-like feel to it which is entertaining.
However, the scenario takes a dive after the ski weekend, because we go right back to the pre-chewed romantic drivel that most Hollywood chick flick try to sell us. The very end particularly could have come from any brainwashed hack of a writer. Very disappointing.
If they could have come up with a good third act, it would have been an amazing movie because the cast is outrageous, the dialogs are good, and the film is well put together.
