Tales of the Jedi is not the first anthology series set in the Star Wars universe; Star Wars: Visions released last year and was comprised of short films created "through the lens of the world's best anime creators", with each episode in a different anime style. I am personally yet to watch the series, but it received glowing reviews. It's a true anthology series comprised of nine episodes spread across the timeline and following new original characters and their stories.
In contrast, Tales of the Jedi had six episodes of an average fifteen minutes in length in the animation style of the Star Wars: The Clone Wars series. My biggest gripe with the series is that it fails to live up to it's title, instead focusing on just two Jedi - Count Dooku and Ahsoka Tano. The episodes are in timeline order starting with Ahsoka's birth, followed by Dooku's fall to the dark side, then Ahsoka becoming a powerful Jedi during and following the Clone Wars.
With Dooku's fall taking place the same time as The Phantom Menace, audience finally get to see what happened to Yaddle and we finally got confirmation that Yoda just speaks weird, not his species as a whole. I found that Dooku's episodes really expanded on his character and actually made his reasons for leaving the Jedi Order more sympathetic. Ahsoka's episodes tie in neatly to Season 7 of Star Wars: The Clone Wars and the aftermath of the finale, whilst loosely adapting yet retconning the 2016 Ahsoka novel written by E.K. Johnston.
The show has potential to develop characters in a way that Star Wars: The Clone Wars wasn't able to and shine a spotlight on minor Jedi. There is so much potential to explore such as what happened to Barriss Offee after her framing Ahsoka for the temple bombing? A second season is yet to be announced but following the timeframe for previous renewals, we should know in a few months.
