I agree Mandalorian was really fun, and it's possible that a future Star Wars show/movie may even exceed that one. But my perspective is that the best has come in the original two films. They won't be rivaled, and anything else is essentially glorified fan fiction at this point. From that point of view, I think taking risks with an unconventional storyteller is a good move. There is always a great risk of failure, but also the possibility of something really interesting and good. Going with Rian Johnson was an example of this, for better or worse. I'll take that over Ron Howard any day, personally.
