The first four episodes are remarkably slow, but I still found them enjoyable. It's just that they weren't what I thought a show about Boba Fett would be. My first disappointment is that Boba's story is almost completely limited to Tatooine. I had hoped that we would see more [read: any] scenes with him hunting bounties in exotic locations (even if in flashbacks). Even after it was established that he was setting himself up as a crime lord, I thought that the show would be more of a gangster-style look at Star Wars.
Instead, it was overly simplistic. The strategies were something that I would have come up with as a young teenager, playing with my Star Wars toys. For that matter, quite a few action scenes almost seemed to play out like an adolescent's play session. The younger part of me appreciated that, but my more mature side (yes, I have one) would have preferred more depth.
In the end, the merits of the show outweighed its faults. I was particularly impressed with the use of practical effects over computer generated animation. While this might impose more limitations (and an underpowered speeder chase), it felt more like the Star Wars that I grew up with. That said, some of the computer effects are quite spectacular too, bringing to life characters that I did not expect to see. This is a show for people who love Star Wars (especially those who followed The Clone Wars and Rebels).
If nothing else, it is worth it to see the continuation of the story of the Mandalorian (and Grogu).
