The Acolyte had rich material with which to work. A time in which the Jedi held undisputed sway over the teaching of the Force, and the Republic as a whole was in a Golden Age. The choice to set a series in this time period was risky, but the potential for intrigue and fan conversation was very high.
The story with the twins is a poorly thought out one. It risks undercutting Anakin at the least, and completing tears apart canon at the worst. The choice to have 2 flashback episodes was a poor one. The show dedicated a fourth of its season to things not happening in the "now" of the show. In my opinion, that choice didn't come about to pay dividends.
If the show had been about the Jedi almost discovering the Sith a hundred years before the Phantom Menace, there would be a lot more to talk about. Instead, they try to make their own story at the cost of what is established in the prequel trilogy. It leaves me thinking that Disney does not give one shred of thought to Lucas' canon, and on principle, I have to oppose that.
The final episode showed that the writers (to some degree) knew why the fans were watching the show. Yet, they did not deliver on the promises in that final episode nor in the series as a whole. As a Star Wars fan, I am disappointed, but I cannot say that I am surprised. It seems that few who are in charge of making Star Wars content understand the content they have been given authority over. It is a shame, but that is just the norm these days.
Maybe a season 2 would correct some or all of these mistakes, but based on this season and the time I spent watching it (that I will never get back), I am not sure the crew behind this show can make a compelling Star Wars story.
