Didn't hate it because it starred women, I hated it because it sucked.
I had no problem with the ghostbusters being female. I'm not one of those who think women can't be funny. The women in this film weren't funny but there were plenty of men in the film too, and they weren't funny either. Hell, 3 of the original ghostbusters were in it and they weren't funny! The problem was with the whole approach and the writing.
The ghostbusters themselves were annoying and eccentric. Look back at the original film and they're actually quite subdued. It's not the funniest film in the world, but when it is the humour comes naturally, it's not forced.
