I was not familiar with the books, on which this was based, so I was a bit stunned, early on, when this took a hard, right turn, into territory that you might not typically expect for TNT. I was stunned, not in a bad way, but simply because it was more like something I'd expect to see on HBO, where they can get away with sex, murder, and just about anything goes (all of which seems to be on the menu here, as well).
Suffice it to say that the main characters are a "bit flawed" (understatement, intended), but, of course, that's what makes it all so interesting. It didn't take more than about 10 or 15 minutes for Michelle to shatter her Downton Abbey image, and chart a completely different course in the acting universe, all of which she handles just as smoothly as she did the role that put her on our radar in the first place.
I'm only two episodes in (the two-hour pilot) at this point, so it is hard to fully judge the motive behind some of the character's actions, but at this point, all I know for sure is that I "really want to see more", and find out where this is all going.
Sorry, but in the effort to avoid any spoilers, I'm being intentionally vague, and leaving out any salient plot details. I'll simply say that this program, although having nothing similar in plot, seems to be in the vein of a program such as "Breaking Bad". You know that you ought not to like the main characters, but you just can't help yourself. Bottom line... I'm already hooked.
