Eh, I feel like the Mandalorian can be objectively "good" though. Just in terms of, you can tell the people are talented who were assembled to work on it. There are lapses from time to time though, for sure.
For some reason I cannot phantom, Netflix and others seem to have tons of money to throw at the production, but don't seem to want to spend more than a few pennies on script.
I tried watching Cursed on Netflix, and had to force myself past the first episode due to the horrible writing. It never got better. The pieces were there for a fairly interesting show but it clearly needed more work on the writing side. Instead they pushed it into production and made another predictable flop.
This is probably true if you take the average person, but there have always been people reading their entire lives, and there has been a mass market for bad literature for hundreds of years. Cervantes was decrying the state of literature and the huge amount of poor, samey chivalric books in 1605.
There is no such repeatable mechanism for original writing. You can find great writing for nothing and pay through your nose for terrible writing. You can find a great writer who delivers a great concept but then she has nothing else in the tank. Or she does, but you can't find another one of her.
You see billionaires buy their way into being big-time movie producers but you never see them buy their way into being big-time screenwriters.
You can love just watch just the "production value" and not to be ashamed to like endless repeating of familiar.
Star Wars franchise also provides frequent scenes of characters taking a posture and saying some short sentence that becomes a meme you can share with friends.
Or you can cram a movie full of it and call it Star Wars IX...
i don't see how the OP's take on the mandalorian is at odds with the idea that the people who make it are probably pretty good at their jobs
