The main alteration to the film is that it trims out the violence, because well, it's a film. Bateman comes off as more misogynistic and homophobic in the film because he's spending less time just being sadistic, it makes him seem like he has specific hangups rather than general detachment from humanity. They get to call this a "feminist lens" when any other film they would beat their chests attacking it for leaning on gay jokes for part of the humor.
I'm not attacking the film for this, I prefer the film, but it's not really a deliberate or major change to his character versus an effect of the medium change.
