I was always a big Whedon fan. I loved Buffy and his initial run writing X-Men comics. I really enjoyed Firefly, Dollhouse was very mixed but had occasional brilliance. (I found his Avengers movies pretty Meh! though.) But I thought how he treated Carpenter was very 'off' when I first heard he speak about it and after his ex-wife wrote about him, I thought a lot of what she said made sense.
Since reading that it made me remember back in the 90s when there was huge buzz around Buffy. There were interviews with Whedon and the cast about how they were all very close knit apart from Sarah Michelle Gellar who more kept to herself. I remember a friend telling me it made her think less of Gellar because it sounded like she was really stand-offish and thought herself the star. But knowing what we now know about Whedon and the woman that Gellar appears to be, more concerned with her family than being show-biz. It makes me think that there was a game going on with massaging Whedon's ego that Gellar just wasn't willing to play. All of which may have played into why Gellar never became the star that she had the talent to be.
You hear of so many young women who start out so promising in the industry but get a reputation for being 'difficult' because they don't play along with men like Whedon, or on the even worse end of the scale, Weinstein.* And then their career falters. This is also true of some young men. Jason Behr seemed to be at the beginning of a promising career until he did a movie with Kevin Spacey, then his career completely faltered.
*(Not saying Whedon is a criminal like Weinstein but it is a toxic industry.)
