I was having trouble articulating why I was never excited for this show, but after seeing the trailer, I think I know why. I think what made the most sense for Obi-Wan’s character was for him to remain hidden on Tatooine and not really do all that much exciting. Grappling with things internally, of course, but not going out and trying to save the galaxy. But in order to make a successful TV show that mass audiences will enjoy, there has to be exciting action scenes and big adventures. I think they should have avoided making a show about him altogether and focused on someone for whom action-packed adventures actually make sense. A Darth Vader show might have had more room for that and could have been interwoven with flashback sequences featuring Ewan MacGregor as Obi-Wan if they wanted to bring him back.
Yeah, I don’t know what kind of plot I first imagined for this show but I always kind of wanted him to just remain on Tatooine and have a story really about character development. There are some great stories about Obi-wan in this time period in books and comics which don’t feel the need to bring Vader or Inquisitors in. Throw in some Force vision stuff, maybe even the trials Obi wan has to pass to become a force ghost like Yoda, and I think you could have a great series which doesn’t tread on the duel from A New Hope.
Unrelated but here’s a video about Qui-gon Jinn taking force ghost form and the possibility of Liam Neeson returning as the character in the series:
