I loved the first three episodes, episode three being my favorite. Even though they were handled by a different director, they all felt incredibly cohesive. Episodes 1 and 3 in particular having repeat locations and characters that don’t feel different when you come back to them. They way the camera is handled also feels very similar and the performances for the background and supporting actors have the right touch to them. I say all of this to say that episode 4 brought on some disappointment, especially in regards to my last point. The entire intro felt incredibly odd and didn’t seem like Star Wars (and I’ve watched all of Clone Wars and a lot of Rebels), and the waitress at the restaurant felt odd. Those two guys that recruit Mando were terrible, and the whole episode just felt really weird. I can only point to the director, Bryce Dallas Howard, for the reason. Truly disappointing since I had heard such good things about her as a director (apparently her episodes of Black Mirror are amazing, haven’t ever watched the show). I loved the action with the AT-ST, and the quieter moments between Mando and the widow, which felt very necessary to his development, and us as an audience getting to learn a little more about him. Hoping episode 5 is a “return to form” so to speak, especially since I believe the woman who directed episode 3 returns for it. Could be wrong, she may be doing 6 or 7. Just know she and Filoni were the only repeat directors, and Taiki has the finale.
TL;DR: episodes 1-3 are great, especially episode 3. Episode 4 in my opinion a disappointment due to poor direction.
