Unlikely we’ll see any of this in the show, but I suppose for me, there will be at least something of value if this show has a few moments of quiet introspection. Give Hayden another shot at playing the Anakin Ben describes in ANH—I know flashbacks can be bad, look at Book of Boba Fett, but just give me a look at a time when Anakin and Obi-Wan were friends. Just a quiet moment at a campfire, or in disguise at a bar or cantina. Something that shows Jedi being people and those two being anything other than antagonistic and jealous of each other. I feel like a scene (or even an episode, or series of scenes throughout an episode) can serve both to remind the audience that these two were supposed to be friends, brothers even, as well as run counter to Vader’s actions and portrayal in the show. Plus, otherwise, I don’t really see the point of casting Hayden if he’s just standing in the suit or briefly in a bacta tank before getting dubbed over by an aged James Earl Jones—or worse, the computer program they use for Luke to de-age the voice.
Anyway, I feel it’s unlikely at this point, and I haven’t sought out spoilers of any kind so I don’t know if it’s already a hopeless dream, but those are my thoughts. I get the feeling, though, that the show will actually be a copy of the EA Battlefront II campaign—overconfident female Imperial extremist becomes “nice” and turns to the good side, and then thinly disguised as a Kenobi show.
