I want to agree, but then you'd have to remake Episodes 4-9.
Exactly!
Everyone wanted to see another Vader v Kenobi encounter in this series. But both have to survive due to the Original Trilogy.
I thought it teed up the encounter in A New Hope rather well. Vader has now lost twice. By that stage he's older as well. It sets up a more cagey lightsaber duel on the Death Star, one without the ridiculous and pointless twirling flourishes.
As for the Kenobi series as a whole. I think episode 6 finished it off well. The point about the Darth name that I mentioned previously was addressed. I liked that. It felt like they did that just for me

.
I'd have liked a longer series, but I can understand why they limited it to 6 episodes. The Book of Boba Fett went on for too long and struggled.

@rhett7660 I thought the best Star Wars series so far, was the Mandalorian. In many ways, though it's an easier series to write. There were no expectations at the start, and it used almost exclusively new characters, save for a few significant cameos towards the end (which they did brilliantly).
What that show wasn't able to do was satisfy Star Wars fans desire to see more of the characters they value the most, including what they did before and after the events of the movies. This is principally what fans (customers to Lucasfilm / Disney) want.
The challenge for anyone doing a story with characters like Boba Fett or Obi-Wan Kenobi is being true to the original trilogy (and prequel films), without jeopardising the sequels (although this is something I am less worried about).
The Book of Boba Fett, is in many ways a great example of the problems writers face.
He's a very popular character. Lots of people know who he is and want to know more about him.
1st question. What's the starting point? What do they have to work with?
Starting with the Original Trilogy, Boba Fett has almost no dialogue and only a few minutes of screen time. However, he has become a fan favourite and a much loved character. Lots of potential scope without jeopardising canon.
Next question, what does a series about Boba Fett need to include?
It needs to include how he escaped from the Sarlaac Pit. It also needs to deal with his transformation into the character he's perceived to be. It can't be just him going around collecting bounties as a bounty hunter. The Mandalorian had covered that ground and it gets stale very quickly.
So, these are the stories they tried to tell in that show, and as we saw, it struggled badly.
The escape from the Sarlaac Pit was spread out over a series of flashbacks, as was his transformation / rehabilitation with the Tusken tribe. Both story arcs had limited tension as we all knew where it was going and how it had to end up. There weren't any credible challenges for the main character to overcome that we could care about along that journey. He was going to live. He was going to become a better person as a result.
The other story arc was his take over of Jabba's palace and crime empire. This was hamstrung by the characters rehabilitation / transformation into a good guy popular culture required him to become. This ended up with him being a crime lord ... that didn't do crime. I suspect this was further hamstrung by the franchises desire/need to sell toys.
That last part was a terrible writing choice, but there it is.
But the end result was that the series struggled all the way through.
Turning back to Kenobi. You can't do anything after a New Hope as his character has been killed off. What you do have are the intervening years.
What does canon say about those years? It begins with the jedi being hunted down, so he can't be as well known / high profile as he was at the end of Revenge of the Sith. The Empire still exists. He was thought dead or forgotten in a New Hope. After Vader tells Tarkin he's sensed Kenobi's presence on the Death Star, Tarkin is dismissive, saying the jedi's light has gone from the universe.
That's the framework you have to comply with, and in the show Kenobi, they did.
What else can they do, consistent with canon? In a New Hope, Obi-Wan does mention "going off on some damn-fool crusade". I'd like to see where they go with that, next.
But they will still need to deal with the framework. Anyone expecting Kenobi to kill Vader (or vice versa) hasn't been paying attention to Star Wars (and especially the movie the started it all, later renamed Episode IV, a New Hope).
As for Kathleen Kennedy, much has been written about her by Star Wars fans ever since The Last Jedi. I looked her up on Wikipedia. She does have a very impressive history in film making going back many years, but I don't think her contributions to Star Wars have been positive ones.
I would also like the reins to be handed over to Favreau, Filoni. I think Timothy Zahn's contributions have been great too.
