Two episodes deep into VT recommendation ZeroZeroZero and really enjoying it! Might have gone a little OTT at the end of episode 2, will have to wait and see. Andrea Riseborough is excellent.
Four episodes in and I'm having doubts about Picard. It's so long since I've watched any of the series I don't know whether the whole Star Trek thing still interests me.
Try the first episode. I think you can enjoy the series on its own and if you're confused, or want more detail, there should be explanations online where geeks congregate.
