I don't think it's particularly important for the series writers to go spelunking through lesser-known alien threats in order to impress me with their imaginative prowess. If you'll pardon the pun, Star Trek is a commercial enterprise, and going for the popular choice is perfectly reasonable as long as they do it well. And they have certainly done that.
For example, I'm grateful that Picard himself is being far better treated this season than in past ones--he's an actual prime mover this season, as opposed to convincer-in-chief.
Do I like The Motion Picture better than Wrath of Khan? Sure. But TMP flopped, and WOK was a runaway hit. Would I love to see the Chinatown or Godfather version of Trek? Absolutely. But I'm not going to fault Paramount (the studio that made both of those) for making a commercial choice in a commercial endeavor with millions at stake. (Granted, Godfather was a smash hit, but it was so because it rode the coattails of the best-selling novel in history.) And I think P3 has been done very well, allowing for the fact that it's adventure-Trek rather than big-concept-Trek.
I will say this--after Rogue One and Andor, I would love to see a Tony Gilroy Trek...
