The only explanation for Picard that one needs is this. Shatner is coming to my town. Which is not a big city, maybe 500K people within an hour each way. 3000 seat venue. $45 each, more for the floor. Showing "The Wrath of Khan", which is a FORTY ONE year old movie that I'm sure anyone interested in this has seen many dozens of times and then Shatner , who is NINETY ONE years old will give what they are billing as a "short talk".
And it will be a sell out.
Picard is just fan service. They make no attempt to produce something that furthers the Star Trek narrative. Just a bunch of actors, none of which have done anything since the show ended thirty years ago, dressing up and mucking about in a video version of a Trekie convention.
