I think Ozark is what Breaking Bad would have been if it had ended up on Showtime. It's a similar story plus the freedom of premium cable TV, but minus the very specific creative trademarks of someone like Vince Gilligan. Ozark is more about straight up plot and shock value; there was quite a bit of that in Breaking Bad too, but it was almost always in service of the show's more literary themes. Ozark doesn't appear to have an overall plan/structure, so it's also not as tightly plotted, which makes some of it feel a little more gratuitous, where shocking events in Breaking Bad usually carried both short- and long-term consequences. If Ozark had a weaker cast I don't think it would hold together nearly as well as it does, but all that said, it's still very watchable.
Aside from being set in the rural South, I'm not sure I see any parallels to Rectify, though.
