I think this episode was Favreau and Rodriguez playing with Star Wars action figures a bit - and I mean that in a good way - but I don’t see that as a recurring feature of the show. I don’t think any characters from The Mandalorian have been any less interesting than characters from the original trilogy.
Oh I have no issue with the characters, I think they’re great. It’s the plot that seems to meander at times, but maybe everything will fall into place in the end.
