I spend most of today in bed with a cold watching SciFi TV shows. Dumbest McGuffin so far: A device that sends messages one-way to the future.
That was season 3 of Supergirl. Now I watch Westworld. (That the video of that piano is newer in sync with the music drives me crazy! Otherwise I like it.) If you want recommendations for SciFi: Firefly, Dark Matter, Humans, Black Mirror, Agent Carter, Orville, Dirk Gently
