The basic premise is that Mark Ruffalo's character is manic-depressive and has had several breakdowns. He tries to reclaim his life and family by attempting to take care of their two daughters while his wife, played by Zoe Saldana, goes to school to get her MBA. It's Mr. Mom, but with bi-polar disorder.
While Polar Bear is rated R, it's mainly because of language. This is a time where I really don't see why it couldn't have been PG-13. Why? Because a movie goes over the quota for certain words? It's stupid, antiquated and I don't think this should affect that rating that much these days. It being rated R might discourage people from taking their kids, but I actually think this is something you should take your kids to see, provided they are mature enough.
Infinitely Polar Bear isn't depressing or a downer, and I actually think that most people will ultimately enjoy and have fun with it. Despite its lighter tone, it has its poignant moments and worth seeing just for the performances. I actually thought it was a good date movie. Infinitely worth a matinee.
