I’d disagree. The show is about a bounty hunter on the run in the Fringe with the kid/bounty he’s protecting. It’s going to have episodes about that. The Cara Dune episode in the village is very much about that - it definitively establishes why he can’t just hunker down and hide out, or try to hide Baby Yoda somewhere. The Tatooine episode and the Bill Burr ep in the prison ship aren’t as directly on-point, but they do establish important character elements and background.
Even if you count those as “filler” episodes, though, within each episode, there’s no filler. Each scene, and pretty much every single shot of each scene, moves the characters and story of that episode forward. The exact opposite of all too many Netflix shows, which have characters standing around talking aimlessly and dithering instead of actually doing stuff.
