I know I've seen some people complain about the episode lengths, but I don't mind. I'd rather see the episodes have different lengths, so they can just tell the story they want to tell in the time they need to tell it, rather than stretch it out or cut it short.
Yes. Many's the time over the decades that I've wished TV shows had the freedom to make their episodes as long or short as the story required, rather than having to insert padding or take out worthwhile material to make it fit a fixed length every time. With streaming TV, I finally get my wish.
Although that's speaking in general. With regard to the Boba Fett premiere, it didn't even feel like a full episode -- more like half of one, just abruptly cutting off in mid-flashback. That's disappointing. What I like about The Mandalorian is that it feels like an old-school episodic series -- it has developing story and character arcs, but each installment tells its own self-contained story with a beginning and end. The Boba premiere gives the impression that this is going to be a single serialized story with each episode just being a piece of it, though it's hard to know for sure after only one episode. (Maybe it's more like there's an opening 2-parter and then it's more episodic, but we'll see.)
