As a Sci-fi enthusiast, it’s sometimes hard to find quality as well as an engaging concept in a series. OA is incredible. It has sophisticated twists and turns, but also captures you on a very human level. The slower story line seems to be an issue with some other reviewers, but I feel it is necessary to really get to grips with the characters and there ‘unusual’ day-to-day lives. I cannot imagine how long it took the writers to nail this series, as it’s so complicated. Having said that, I didn’t find it so confusing that I lost interest - quite the opposite; I was on the edge of my seat for every single episode.
