I watched this as I'm a keen photographer and hoped to learn more about Arbus despite the film being honestly marketed as mostly fiction (the other main character 'Lionel' and anything about the family other than their existence) based loosely on an unauthorised biography. I learned how to pronounce Diane but not a lot else. That doesn't make it a bad film just not very educational. It's a good idea for a film but doesn't quite hit the mark. Given the artistic license it affords itself it could have gone anywhere but it doesn't really. There are some interesting, quirky and funny bits in it but... read the rest.
