I've read a lot (not all) of the posts on this site and it seems like a common element that is missing is how bipolar disease impacts the movie. I am 54 yrs old and have Type II Bipolar disease (more depressive and occasional manic swings but not wild swings). To me, even though the movie had a Hollywood storybook ending for entertainment value, there were a lot of nuances relating to bipolar that wouldn't be obvious to those who aren't familiar with the disease. This had an impact on making this a non-traditional romantic comedy, which made the movie different than a number of people were expecting. Here are some tidbits of bipolar and how they are intertwined into the movie: (1) bipolar is a chemical imbalance that you are born with, it usually presents itself in your teens, and you often don't know the true diagnosis until in your 30's or 40's, often after something dramatic has happened; (2) unlike one of the posts that said Bradley Cooper wasn't believable because he didn't look "crazy enough," bipolar doesn't produce people looking like Jack Nicholson in The Shining--they are everyday looking people who are just wired differently and act differently; in fact, we are good at making an effort to "look normal" because we try quite hard at it; We know inside that we are different than others, but we look at how other ?normal people? look and dress and try to be like them; (3) bipolar people wreak havoc upon families, loved ones, co-workers and most other people around them; they lose their jobs, spouses, etc.; This is very common and part of the early part of the film; It didn't happen to me because I "worked on things" to stay within the white lines of life; I have a wife, three kids, own my own business, etc. For many undiagnosed bipolar people, they are somewhat functioning in society but labeled "difficult to deal with and be around"; (5) it is not unusual for bipolar relationships to lack "chemistry"; these are typically socially awkward people who try hard to be normal but it isn't always a smooth ride; and (6) as far as the storybook ending, sure the movie was fantasy, but where it fits into bipolar is that people with this disease wander through life with a lot of ups and downs and are searching for meaning. When they find it, especially with someone they enjoy, then they are "all in" and it becomes meaningful to them even if it isn't meaningful to others. The movie wasn?t traditional as far as movies go, but it was pretty good at depicting the dysfunction that goes on in the life of a bipolar person. I enjoyed this fantasy very much. Finally, SORRY ABOUT THE LONG POST!!!
