None of which means that the relationship didn't grow out of a dynamic that was positively horrific. Dany was on the edge of suicide by the time she found the strength (in large part from the connection she felt to her dragon eggs) to adapt to the lifestyle of the Dothraki; the freedom she briefly felt from her wedding night was long gone, and she was trapped in yet another prison, this one more immediately brutal and seemingly impossible to endure than anything she'd experienced before; while Viserys was controlling and nasty, he never approached the level of brutality that Dany experienced in her first several weeks with the Dothraki, very much including (and amplified by) the nightly sex from Drogo.
The point is that if Drogo is just another person controlling Dany like Viserys or at least establishes himself as that in her eyes during their first encounter, it makes the transition to the person who "gives her the wind" a lot less believable. In the books, he's like the first person ever to allow her some control of her destiny, and he establishes that immediately on their wedding night. It's a small thing but it's meaningful to her and goes a long way to explaining why Dany could come to love Drogo the way she did.
The fact that love grew out of that awful beginning had very little to do with the relative pleasantness that she was finally allowed to feel on her wedding night. Yes, Drogo represented freedom from her previous prison, and yes, in some ways he showed that potential on their wedding day and night, but far more important was the fact that, when she began to take charge and to renegotiate the terms of their encounters, he responds positively, and changes to suit. That was why she fell in love with him, not because of any specific characteristics he showed on his wedding night.
The dynamic that the show is setting up is more or less the same, just without the added complication of Dany's sexual awakening coming from a relatively pleasant wedding night. The relative brutality (although, I hasten to add, not nearly as objectively brutal) of their later encounters was transferred to the wedding night, probably in the spirit of expedience and to give her a similar place to grow from. I don't see how that transference makes it somehow less believable that she comes to love him, period. No matter how you slice it, book or show, their love grows out of a place that is brutal and uncomfortable to modern eyes.
