Realistically, Kenobi could be set exclusively on Tatooine, and I’d have no issues if that was what they did. The problem is that they chose to set so much of Mando and BoBF on Tatooine, also. That was the mistake. People are getting Tatooine fatigue now, right when we’re getting a show where it actually makes sense to have Tatooine.
Tatooine fatigue? People who do not like sand are dangerous, or should be ignored! 😉
It would be a welcome move to see more Star Wars releases in new locations or other lesser-seen locations, but for this it is understandable.
I am hoping the series will not be too “light” or “uplifting” as described below.

We will have to wait to the see the series itself, but I think I would have preferred a darker story for this show, in contrast to other recent Star Wars shows, given the context and situation of Obi-Wan, and the weight of responsibility and burden upon him.
