Honestly you can only blame Lucas for the terrible dialog. The actors didn't write the scripts. Also we all know there's like 100 takes of every scene bout those where the ones chosen by the editor. Hayden Christensen just did the job he was paid for, to the best of his abilities. You should watch Icons unearthed: Starwars. The interviews with Lucas's ex-wife and principle editor of the original trilogy really brought the process into perspective.

The show didn't fail. The plot was a bit messy and the Mando problem is obvious. But I have said time and again the perfect story going forward already exists. We already know from Bad Batch that Boba is Alpha and his twin is Omega who is now alone in the galaxy without her clone brothers. It's time to bring them together.
