Re: Talk To Her.
It's not really a literally realistic movie, I don't think. It's a parable, and in an every-day situation, what Benigno did is obviously unacceptable and immoral and like you said "ew..", but depicted in the film it's the bridge to a moving ending about rebirth, love and sacrifice.
I think you should definitely see more Almodovar.
I agree though that the other guy's storyline is better, and I think that actor's performance is incredible.
Are you catching up with films from this decade you haven't seen?
