The problem with the mandalorian is the writing not the effects of set dressing. I never watched past the first season because the writing was very poor.
It seemed to be me it felt like a deliberate style decision by the creators, a throw back to easier going older shows that I grew up with in the 80s and 90s.
This may not be for everyone, but I found it very easy going, slightly amusing at times and a refreshing change from the current typical high budget TV series which seem way more serious.
