I saw it, in the theater. I didn't find it depressing or bad, per se, but it was very obviously a flight of fantasy regarding her life, not a legitimate biography. While I understand that the Arbus estate is very controlling of access to her work and her papers, and won't help anyone who is not trying to write a glowing paean to Diane as a "normal" person, I fail to see why this movie needed to be made. Without being able to factually re-tell her story,what's the point of a "fictional" biography? It's only slightly more historically accurate than "Inglorious Basterds", which at least had the benefit of being highly entertaining. This was just baffling.
