I haven't read the books, but I did see the movie. And the movie isn't all that bad. The only abusive part in the movie is toward the end. Ana asks Christian to punish her, because she has to know how bad it can be. After the punishment, she screams 'don't touch me! Is this how you want to see me?' Then, she leaves him.
But I read a few things from the books and those things seemed rather disturbing. So, my guess is that in the books they're relationship is abusive, but in the movie not so much. Of course, my opinion could change once the second and third movie are out.
