The only storyline I found somewhat appealing was the one with Jennifer Aniston and Ben Affleck - she basically issues an ultimatum and actually follows through with leaving him when he won't marry her after 7 years together. They get back together when she realizes that having a man who loves her and who IS committed to her even if he doesn't want to pin the label of marriage on that commitment, is more important than having that label. I would have felt the movie was actually worth my money if they had ended with that and shown a couple that was truly happy and committed without being married, but I guess that's too much to ask for.
Part of what was so disappointing is that I'm actually a huge fan of the book. I know there are plenty of women out there who think it's too simplistic but like Miranda in the SITC episode where the phrase first appeared, I find the idea liberating - forget the games, give up the drama, just accept that he's not into you and move on. In the book (but, I felt, mostly missing from the movie), Greg Behrendt makes the point repeatedly that we all deserve someone who recognizes our fabulousness, that if someone is not acting like he's into you, you deserve better. And the first time I read that, I did my impression of Carrie Fisher in When Harry Met Sally - you know, where she keeps saying "you're right, you're right, I know you're right" when Meg Ryan tells her that her married boyfriend is never going to leave his wife. We all know that we are supposed to be with someone who thinks we're fabulous and that we should walk away from anyone who doesn't treat us as we deserve to be treated. However, what Behrendt doesn't tell you in his book (and CERTAINLY is not shown in this movie) is how to do that, how to stop wanting someone who isn't into us, how to actually walk away and let it go.
The problem is that you have to have a certain level of self-confidence to shrug it off when someone (who you presumably are into) is not that into you. There's an irony here that took me years to appreciate: if you think you're awesome, it's a lot easier to accept that someone else doesn't think so. It's not personal, it's not damaging to your own self-esteem, so you don't need to dissect it, you can just let it go. And the even more ironic catch-22 is that the more you chase after people who are not that into you, the harder it is to find that self confidence, but actually BEING with someone who believes you're fabulous - or simply surrounding yourself with supportive friends who always make you feel great about yourself - can't help but make you feel more self-confident.
I wish they made more movies that showed that!
