SPOILER RE: Shutter Island
I thought Shutter Island was very positive regarding psychiatry. Although they were to lobotomize him at the end of the film, the amount of time they spent with him indulging his delusions was remarkable. And most likely they thought the lobotomy the right thing to do. I can't imagine that in real life any patient would receive that much attention.
END SPOILER
As far as this movie, we don't know that it demonizes psychiatry. Given that it's a thriller, it's probably not going to be what the trailer suggests. I've seen at least two thrillers with demonic dentists, but I don't think they caused mass hysteria about dentistry. One Hour Photo was one of the creepiest thrillers I've ever seen, and it was a guy who worked at Walmart. So, in this movie the psychiatrist is the vehicle as the perceived villain. Most of my jobs have been in customer service. If there were a thriller with an evil customer service agent, I don't think I would be upset by it at all.
Re: Catherine Zeta Jones and the previous comment, my own opinion, is that we should treat all people as if they have all the layers of a human being. Psychiatry by definition is about treating the mind and soul. I'm not sure why Jones should be pigeonholed as a psychiatric patient who has to be a poster child for bipolar. Isn't the idea of medicine to restore functioning to a person so they can live as much as possible as if they didn't have the illness? Why turn down a good role? It's a better gig than T-mobile commercials.
Plus, we don't even know what the movie is about! It could be pro-psychiatric drugs for all we know.
