I'm not quite so critical of the music. I kind of appreciate the Western take on the theme, at least. But yes, sometimes the musical accompaniment
is just boring.
Yes, I agree that the bigger problem is with the lack of storytelling ambition. Mandalorian basically is Star Wars now. They're taking in bits of Dark Empire and the EU, and those had some gravity. Fighting the empire is still a clown show in this series, though, and I don't know where they can go with villains now that they're nerfed the Empire.
Some of those characters from the cartoons are beloved, and I am sure Ashoka will get first-rate treatment. She'll be in her own series, though. I hope now that the backdoor pilot episodes are done, they can focus on Mando's story and the anarchy after the Empire in a more mature way.
