I am still baffled that anyone thinks this show is poorly done. It is a hit with fans in general and the only reason it will never be as popular as The Mandalorian is that it doesn’t have Baby Yoda (possibly the single most popular character in all of Star Wars). But the production quality of all of them are top notch. I can’t see any issue with the set, costumes, acting, anything.
Many of the sets appeared cheap to me. The city on Daiyu looks great in some shots, but other times (particularly scenes where Obi-Wan/Leia are walking down crowded streets) it looks like a cheap set with extras hanging around in the background. The drug-lab and prison cell looked like a sound stage. In many ways, George Lucas’ 2010 test footage of the Coruscant underground looked better - or at least felt more “alive” and atmospheric due to superior lighting, sound effects and background details contributing to the ambiance.
The picture quality in Obi-Wan also appears more like a television show and less like film. The Inquisitors look like cheap rubber Hellraiser knockoffs. I think a lot of this comes down to the lighting. There’s other little things as well. Mandalorian and even Book of Boba Fett had amazing original scores. This show has no particularly memorable original scores (yet), and doesn’t even reuse older themes that could breathe some much-needed life into the series. I mean, would it kill them to throw in some Imperial March here or there?
