I feel like there can be a general, unmerited disdain for episodes that feature what I call the "A Piece of The Action" factor, when instead of space or alien world themed settings, Star Trek uses the much more affordable period sets/costumes of Earth. It takes a special kind of plot to put our futuristic astronauts in those scenarios & have it play well to a sci-fi audience, who are eager for space fantasy. Time travel concepts help a lot. Holodeck stories pick up some of the slack (which
The Royale flirts with being)
I'm always forgiving of this aspect, IF there's some kind of good concept behind it, especially since I understand that it's helpful budgetarily. I wouldn't rank
The Royale as the best of those, but it's got something to go on, tying it to the dead astronaut, in an inventive way. It's a smarter premise than just "Oh, this world is inhabited by 20s gangsters, because cultural pollution" lol.
My only gripe with this episode is Picard so snobbishly finding the book to be crappy. My dude... You play a noir detective on the holodeck! How much better written can Dixon Hill possibly be? I've seen some of those programs, my guy.
