Venus and Serena Documentary

Has anyone seen the Venus and Serena Documentary yet?

I rented it on iTunes this weekend and really enjoyed it. I have a love/hate relationship with them as a fan, but the documentary really showed them as people, not just competitors. It really focused more on Serena. And I didn't think it was that harsh on their father at all; at most it alluded to some things about him that the family obviously just refuses to talk about (as in it's the secret that the whole family knows but never refers to).

I'm curious what others reactions were & what parts really stood out for you.
