Russian Doll (Netflix Show): This show is excellent. And no, it is not about a Russian and is not a spy show (which is what I thought it would be from the title).
However word of warning. It's 8 half hour episodes. Which sounds small and manageable. However, it's definitely driven to make you want to keep watching. You are very likely to want to binge all four hours in one go. And at the end it feels like one long movie. So, if you're going to give it a try (and you should) make sure you have 4 hours to do it. Because you won't want to turn it off until it's done.
