I think this series has a lot of charm, Hera is very much the I guess Princess Leia of the group, holding everyone together and being the moral center of the group.
Sabine is like Ashoka who started the clone wars as the young girl looking for adventure and is a bit rebellious but she eventually became a bit hard. I can see Sabine doing that as a Mandalorian.
Zeb and the droid are there for comedy and are a bit disposable at some point.
By the way the darkness is coming in the next episode
