Movies about mental illness are notoriously difficult to get right. They make things up, or they come up with atrociously bad treatments, or, even when they base the movie on a true story, they whitewash the details.
The worst part is that they almost never get the actual feel of living with and loving a person with mental illness. The “oh, no, Dad’s riding a bike in his underpants again” aren’t actually as hard to deal with as the daily “oh, Dad has to put vodka in his orange juice or his hands shake all day.” Or the “Mom’s been asleep for two days because her doctor can’t get her meds right.”
But Infinitely Polar Bear maybe, just maybe, will get it right. In part because it was written and directed by Maya Forbes based on her own childhood experiences.
And if nothing else, Mark Ruffalo and Zoe Saldana make a super hot couple.
