I recall rumours of Whedon, super feminist, apparently using the old casting couch routine with young aspiring actresses. Sarah Michelle Gellar apparently hates him, but I think that's probably more down to how hard he pushed and worked her during Buffy. She claims it was ridiculously long hours and way too much pressure, and reading through the lines that has to be aimed at Whedon as she doesn't seem to have a nice word to say about him
Always found his obsession with Eliza Dushku weird too. Though she's never said anything bad about him, so who knows honestly. The amount of people claiming he's a knob are growing though. For someone who just five years ago seemed so likeable and at the very top of the business, it's quite the fall
