I've seen all the ones you mention, UCMATH except for Melancholia (so can't give a comment on that). I hated SLP too!! Especially couldn't stand the portrayal, but ugh on being a crap formulaic movie as well! (There have already been a number of threads on that movie if anyone wanted to search it.)

I liked all the others, though it's been awhile since I've seen them. They each have their own strengths and are different from each other.

Harley, I'd recommend you watch any/all of them for yourself before sharing with BF. Sometimes things just resonate better with our own personal experience, which is what you're trying to convey to him. So see which do that best for you.

Because for the life of me I can never get youtube stuff to just post as a simple link, just add

Homeland I watched (on dvd from library) for the express purpose of seeing how they portrayed it, and I have to tell you, there were junctures where I was struck by what a good job she was doing. Maybe not everything every time, but parts that come particularly to mind….These are all from Season One. She goes manic and has a breakthrough theory and is color coding her "thinking wall" or whatever they call them. I believe it was episode 10 (Marine One). It is possibly episode 11 (The Vest) but I think that is the hospitalization part. "My kingdom for a green pen!"
Depression is shown in episode 12 (Representative Brody).
