Just watched it...meh, not impressed at all. Maybe it is just my particular form of bipolar, but I couldn't relate to these people at all. My bipolar is mostly mania, sometimes extreme mania. The people in the movie seemed mostly depressed and melancholic. I relate more to extremely grandiose lunatics. I found myself zoning out about 20 minutes into it, and it never got any better.
Personally I relate more to fantasy characters, like my avatar of Anikan Skywalker, or the risk-taking maniacs in "Point Break." But that is just me, I have a hard time relating to people who dwell on their depression and suicidal tendencies. It bored me.
I once went to bipolar support group and I hated it! A bunch of people sitting around whining about their depression. There were even a few uni-polar depressed people there. I went a few times, and every time was totally focused on depression. There were only one or two other bipolar type 1 maniacs there, and they were mostly quiet, probably because they were bored like me.
