k, before I launch into this, I just want to say that this show is good and I enjoy watching it each week. Having said that, let's go:
This show has a very '90s, Star Trek, Stargate, Farscape kind of feel (this week was veeeery Farscape), where a season of TV meant 22 episodes at 45 minutes a pop and a lot of those episodes were just kinda there. Just, like, yep, that was an episode. It was a simpler time, when an episode of TV was broadcast and then more or less forgotten until you saw it as a rerun a few years later, and people just thought of TV shows as those things you watched when you remembered to. Individual episodes were almost treated as disposable; it didn't matter if you forgot to watch TNG every second or third week. I don't think even the showrunners expected you to watch every episode back in those days.
I don't like Old TV any more. I think New TV, where seasons are shorter and focused on an over-arching story and long-form character development with minimal filler, is just a better format for entertainment. 13 episodes is better than 22, 10 is better than 13, 6 is better than 10, even 4 is pretty great sometimes. I've seen excellent 3-ers. I don't necessarily think a serialized, adventure-of-the-week show is automatically bad, but in this day and age they'd better be really good adventures, and to be honest I'm still going to want an over-arching story.
The thing that kept you coming back to those '90s shows was a cast of regulars you loved seeing every week, even if the episodes themselves weren't particularly memorable. The Mandalorian only has two regulars, though: a man who rarely talks and and his son who can't talk, and Mando himself has nothing going on in these standalone episodes. Remember when I said I was impressed that they weren't just making him an effortlessly badass cool guy in the first two episodes? I have to take that back, because that's exactly what he is now. This week there was a whole scene devoted to the supporting characters being impressed by his stylish combos on those droids, and then he Batmans everyone at the end and flies away not looking at the explosions. I thought he was shaping up to be something different in the first few episodes where the story and character development were still happening, but now it really is just cool armour guy doing cool stuff.
Without an over-arching story or a compelling cast of regulars, it leaves a lot of heavy lifting to the guest stars and the individual episode plots, and so far it's just been Star Wars versions of things you've seen a dozen times before. Seven Samurai but Star Wars. Heist movie but Star Wars. Crazy knife lady but Star Wars. Big angry Buffy bad guy but Star Wars. Bill Burr but Star Wars. And I like Star Wars (perhaps I've mentioned that), but not just as a new lick of paint over some rusty old tropes.
Like I said, I don't dislike it, I still enjoy watching it, but this isn't what I hoped for when I heard that Disney was dumping money into a Star Wars live-action TV show in 2019. I really hope the Obi Wan show isn't going to be like this.
