Don't like her at all

Well, you ask why is she horrible then immediately start talking how great she was in a movie that you probably liked. Me, I wasn't talking about her as an actress at all! I've seen 'The Master' maybe 4 or 5 times partly because of how professionally she was cast. So... you really should structure your replies better. No disrespect but still.

As to the question why is she a horrible person. Here's how it is. Everyone knew Kevin Spacey was gay, everyone knew that years before he came out, obviously, no one had what you call 'solid proof'. But no one needed it. Some things are obvious, particularly after you acquire life experience, meet a lot of (and I mean really a lot) people and reach a certain age (unfortunately).

So there was always someone on the boards demanding 'facts', engaging in quarrels, asking the usual 'and you know this exactly how' etc. And this was really boring. You have to read people in order to understand certain stuff, or switch between several girlfriends that represent basic psychological types, notice how unrelated people that look similar also behave similar etc. etc. But... I'm sorry to put it like this - some people have it, some never will.

Wrapping it up: In my personal opinion she is a horrible person and I like her just fine.
