Very much looking forward to this. A few thoughts.
It is so random that Werner Herzog is in this. Is he going for an Australian accent and, if so, could he possibly be Boba Fett? His line in this implies he knows bounty hunting from the inside. That would mean the show takes place closer to TFA than RotJ to account for his age. I don't think Herzog is Boba, but it is possible.
If this turns out to be as good as it looks, and is as successful as it deserves, then I wonder if it will be the first stage in Star Wars transitioning more to TV. What would be interesting about that is that while we've seen TV series translate to film (e.g. Star Trek), we haven't really seen a film franchise transition to TV, at least not with great impact and success.
While I like the mystique of the Mandolarian mask, I really hope they don't waste such a good actor as Pedro Pascal. He was great as Oberyn, but a more nuanced role is the under-the-radar excellent scifi film, Prospect. Highly recommended.
