If you enjoy feeling unsettled, episodes like “Mazey Day” and “Playtest” experiment with horror; if you prefer something lighter (it’s not all so bleak!), “San Junipero” and “Hang the DJ” are delightfully romantic. ... A list of sci-fi drama recommendations would be incomplete without Lost. J.J. Abrams, Damon Lindelof, and Jeffrey Lieber’s series begins as an exploration of how a disparate group of plane crash survivors work to stay alive on a mysterious island while learning how to leave their pasts behind them, but it quickly becomes so much more. Over time, the group discovers they’re not alone in this strange place, and are forced to deal with the fact that there may even be supernatural forces at work, far beyond what any of them could have expected when they boarded Oceanic Flight 815.
