If feminists were actually all about equality, they'd love this film.
How many films before this one showed men as dangerous, mentally disturbed stalkers?
The Bird with the Crystal Plumage, Four Flies on Grey Velvet, Schizo, When a Stranger Calls and pretty much every single male slasher character from Norman Bates to Michael Myers.
Now think about all the feminist complaints on this board about Alex. That there aren't any reasons for what she does, other than she's a psychotic monster. That she is largely defined by her relationship to the opposite sex. That she is manipulative etc. etc. I really can't think of anything that's wrong with her that isn't wrong with literally dozens of her male counterparts.
Part of treating women like men is acknowledging that they can be every bit as dangerous, violent, evil, perverted, abusive and exploitative as men, and acknowledging that women like Alex exist in real life, (like Neelam Darr) just like men like Norman Bates exist in real life, (like Ed Gein).
The way feminists go on and on about this film, I expected every other line to be about how all women were crazy, dangerous bitches who couldn't be trusted. But this film has NOTHING like that. Beth is strong throughout the film, Dan has plenty of female colleagues who are perfectly level-headed. Alex is the only one who is not.
Frankly, I cannot see any reason to complain about this film's portrayal of women other than objecting to any woman being portrayed in a negative light, in order to further an agenda of treating women better than men.
