It's Complicated

I was on the treadmill at the gym yesterday watching some garbage TV. My gym has those awesome treadmills with the built-in TVs so you can watch whatever program you prefer. I always choose garbage TV (think TLC reality shows). Anyhow, during a commercial break, I saw an ad for the movie It's Complicated. My first thought was, "No. This can't be right, this can't be a movie about long divorced parents who, years later, get back together. No freakin' way."
As a devoted 30 Rock fan, I think Alec Baldwin is hilarious. That aside, his acrid custody battle with ex-wife Kim Basinger was all over the news a several years back. He was a huge advocate for father's rights and one of the first to publicly acknowledge parental alienation. He knows first-hand the horrors of divorce.
Yes, he hit a wall and left an angry phone message left for his daughter a couple of years ago, a message that was, in all likelihood, full of rage towards his ex but horribly misdirected. There is no excuse for that behavior, but I think many of us in stepfamily situations can understand how such a mistake can be made.
Knowing all of this, I am completely dumbfounded on why Baldwin would choose to act in this movie. Granted I haven't yet seen the film and maybe I'm making a mountain out of a molehill. Here's the synopsis:

Jane (Streep) is the mother of three grown kids, owns a thriving Santa Barbara bakery/restaurant and has—after a decade of divorce—an amicable relationship with her ex-husband, attorney Jake (Baldwin). But when Jane and Jake find themselves out of town for their son’s college graduation, things start to get complicated. An innocent meal together turns into the unimaginable—an affair. With Jake remarried to the much younger Agness (Lake Bell), Jane is now, of all things, the other woman.

Umm, ew! Alec? You're playing into this whole thing after what you've been through?
I'll freely admit that, for me, being a second wife comes with a big fat wad of insecurity. My husband met his ex-wife when he was 15. They dated 5 years, then she got pregnant and they married 3 years later. She's been in his life for nearly 20 years. Me? 6. They have a kid together, the first child for each of them. They have a long (albeit twisted, angry and hurtful) history. The wacked-out soap opera in my head is full of fears of the two of them reconciling at some later date in their lives, like the birth of a grandchild or some other significant kid-related event. (I know this is so very unlikely, but that doesn't mean I don't think it!)
So when I saw the preview for this movie and then did some reading up on it, I wasn't thrilled. I don't know how it ends or any of the plot dynamics, but the whole premise just makes me ill. I don't need an all-star cast making light of my insecurities! Stepkids, adult or otherwise, don't need more media playing into the happily-ever-after fairytale bs. Between Stepfather and this, I'm gonna say 2009's theatrical portrayal of stepfamily life is, well, bunk.

If any of you see the movie, please let me know what you think.
