Profane in its concept, even the "cute" actors don't make this a worthwhile film.

Rating: Null/10 (10 June 2011)

There was a time not long ago when dialog in movies pointed you to what might be happening, and the rest was formed in your own mind. You could make it as clean or as profane as you wanted. Not anymore, even the cute blond 20-something script writer for this movie spells everything out, with very base descriptions of body parts and body functions. It may work for teenagers but it doesn't work for thoughtful adults. It makes the whole movie come across as profane and dirty just for the sake of "dirty."
Then there is the overall concept, that it is just fine and normal for two long-time friends, now adults, to just hook up for casual sex any time either of them is horny, because that serves the same function as a good bowel movement when you are bloated. I am disappointed that fine actors chose to play these roles. The critic Ebert has an excellent review.
The girl is Natalie Portman as Emma and the guy is Ashton Kutcher as Adam. The best role however is Kevin Kline as Adam's dad, Alvin, who ends up hooking up with Adam's most recent ex-girlfriend.
I may be one of the few who recognized Cary Elwes in the low-key role of Dr. Metzner. Although he is nearing 50, with his youthful features and a light beard his character could pass for 35.
Not a very good movie at all, but those who enjoy profane comedic situations will likely enjoy this.
SPOILERS: Naturally Emma and Adam cannot go on forever with a no-commitment, casual sex arrangement. She is afraid to commit to anyone, but he loves her. When he expresses his love and she retreats, he calls it quits. But eventually she misses him too much and they end up together, happily ever after.
