Those are all excellent shows! I think Dark and Fleabag my favorite and easiest for you to binge. Battlestar is amazing but will be more of a commitment. I actually liked Ozark S2 better than S1.I keep meaning to start or keep on with a dozen shows I have started....but on the nights I have TV time, I keep going back to my re-watch of Mad Men. It's so excellent.
I am two episodes into Years and Years, two into Dark, halfway through Big Little Lies, stuck somewhere in Battlestar, I haven't started Handmaids S3 yet, Fleabag is on the short list, as is Killing Eve. And, Ozark S2 seems like one I should watch. I guess that's what winter is for.
