Lots of unrealistic expectations here.
It’s a modern TV series. That means generic entertainment/storyline and production values limited by time and cost-cutting. It’s not art, it’s a (more or less rushed) product for binge/consumption.
And it’s from Disney, meaning the focus is on a broad audience and merchandising. They specifically avoid complex themes and try to make things suitable for younger people (defusing tension through humor - Leia’s pursuit, redemption arcs - Reva, etc).
So it must be compared with other similar TV series, not with movies. For what it is, I think it’s really enjoyable.
