I have not seen this and I'm already annoyed by it. (Yes, I know I will be attacked for writing a review without actually having seen it!)
Let me explain myself. If you think this is a serious meditation on "mental illness", that somehow Hollywood and these actors took a "risk" and "stepped out of the box" to try to give weight and insight into a subject not oft broached by media, let me just tell you a few things:
1) The idea of two super good-looking actors, one the "sexist man alive" and the other uber hot and sexy in Jennifer Lawerence, portraying characters in a supposedly "serious" take on mental illness, is an immediate indicator that this is not a serious film.
2) From what I've gleaned from the film -- and I don't know all the details -- the characters don't appear to have jobs, live with their parents, "middle class" parents who seem to live awfully comfortably. This just smacks of a film not taking any serious risks or trying very hard. It gives the two main leads plenty of time to gallivant around and ham it up.
3) Its take on mental illness and bi-polar disorder already sounds trite from what I've read. I spent many years dealing with my mother who had bi-polar disorder (which I still think is a label used by the psychiatric community rather than anything grounded in hard science.) If the film really wanted to take a risk, they might look at the billions in pills psychiatrists push and peddle to naive patients, and the often lifetime of dependency and serious side effects these drugs cause. Of course, some drugs do work, and some cases do require medication, but it has become a cash cow -- and now what might otherwise be a guy who is just a little emotionally unhinged after his wife cheated on him, and not really mature enough to be able to handle it, is now "bi-polar".
4) The rom-com silliness that happens at the end has nothing to do with the actual REALITY of mental illness, which very rarely ends with a happy ending.
Again, if it's a film made to entertain, I have no problem with that -- but it is being regarded and marketed by idiots who have no idea what they are talking about as a "serious" film, somehow a possible Oscar contender for Best Picture.
Of course, I have NOT seen this film, and I may even enjoy if I see it -- I probably will, because David O. Russell usually puts out a good product -- but let's not confuse what this really is: cheap escapism and hi-jinks, Hollywood trying to be serious and laughably failing. It's enough these morons feel the need to regale themselves with numerous televised award shows that they have to slap themselves on the backs for doing something "serious". Just... stop giving these idiots your money and give it to a local theater group instead.
