Eh, it's hard to see it any other way for someone not familiar with the book, she's crying, she obviously doesn't want to do it, and Khal seems less compassionate than in the book. I mean I don't think it's bad, as it's probably slightly more realistic. very reluctant would be putting it nicely I suppose.
You're right. Cutting away implies that it was most likely rape, leaving her in peril and drawing more sympathy.
My pre-conceived notions of Dany and Drogo clouded my judgment there.
