The thing is, a lot of the stuff we’ve seen from Disney+ Star Wars seems unusually and atypically bad - suggesting problems that go beyond the typical writing and development mishaps you’d expect from most mediocre productions. The biggest example of this is probably undoing the entire Mandalorian Season 2 arc - by shoehorning in a subplot in an entirely different show no less - presumably because Disney execs were terrified about the prospect of losing baby Yoda.
Also, while Mandalorian Season 1 and 2 are overrated, they didn’t quite fall off into the abyss of bad writing like later shows. Apart from Andor, it seems there was a steep drop in quality beginning with Book of Boba Fett and Mandalorian Season 3. Because this drop in quality occurred at the same time as the bizarre decision to back track the entire season-level arc in Mandalorian, it’s difficult not to assume there was massive studio interference leading to things like demoralization or apathy among writers. At least, it feels like some people like Jon Favreau may have just checked out creatively after that.
