I watched 6 episodes of The Mandalorian. Not really delighted. No depth, no character development...
Then watch four episodes more.

Well, I guess it's a slow burn, the show has more of an old-fashioned structure, as in a string of loosely connected one-off episodes. They do lead several of them together in the serie finale though, and set up a path for the second series.
I enjoy it a lot, actually more so than most other Star Wars I've seen (which basically comes down to Episodes I to VI). Fewer annoying characters, more fun with the setting. (But then again, I also think "Better Call Saul" is way better than "Breaking Bad", for much the same reasons.)
I'm currently about halfway through
"The Expanse". It took me three tries over the years to get beyond the first one or two episodes, and I don't regret giving it another go. Some of the stuff makes no sense at all, some of the stuff is very trivial writing, but the character development mostly works, and sets and CGI are quite impressive for a TV series.
