There have been many Star Trek spin-offs. I do not really follow them. When looking for a bit of a quiet series to watch, I gave this one a try. This spin-off -of course- has Patrick Steward return to the Star Trek franchise.
There are three seasons with a variety of stories. Picard has retired and lives on a wine farm. We are in some time in the future in which several of the kinds of beings that we know from earlier Star Trek material coexist. Usually picard is asked for help, he has to talk his way back into Starfleet to obtain a ship, is confronted by missteps in his past, but manages to go on his mission.
There are references to earlier Star Trek films (and series?), old characters return and in a way “Star Trek: Picard” is a bit of a reunion.
There is more action than I remember in other Star Trek material that I know. The series are fairly predictable, but alright watching.
