I just binged Obsession straight through last night - 4 episodes. It's an erotic thriller, and it's kinda cheesy, but for Netflix it's pretty BDSM-y, and sometimes hot. The male lead was kind of boring (he always looked constipated), but the woman was good (and believably sexy). It's worth the watch.
It's based on a really good book called Damage (which was a movie too, but not a good one). So I watched long enough to hear my favorite line--"Damaged people are dangerous. They know they can survive."--and by then I was deep enough in to finish it.
