I haven't watched it so probably not all that helpful, but I rarely find TV/film portrayal of DV realistic.
Agree with the pp that abusers are portrayed as monsters and usually the women weak and timid.
I also find that the violence is always very in your face.
My ex was very clever about the violence he used to used, he'd never really hit me outright, he'd bite me, pinch me, squeeze me, strangle me, hold me down or pull me around by my hair, throw drinks over me, turn on me during intimacy suddenly trying to force his whole hand inside me, he'd name call, break my things, hide my clothes, all things that no one else could see, not easy to cover a black eye and people ask questions, but easy to cover a bite mark on your arm. And of course then he could say 'I'm not a woman beater, I've never hit you'.
How can you be abused by somebody who's never punched you in the face? The abusers in the soaps don't bite you until they drawer blood so how can it be abuse?
