Overview:
Tales of the Jedi is well-animated and has some strong emotional moments. But, simply put – there’s no reason for these stories to be strung together.
Dooku’s three episodes work when they’re all consecutive – you get a glimpse into his doubt of the Republic and Jedi Order, leading into his fall to the dark side and service to Palpatine. (His actions in these episodes fit very well with his journey in Dooku: Jedi Lost.) But nothing in these episodes links him with Ahsoka. Even the largest factor that the two of them share – that they both left the Order – is never addressed on Dooku’s part.
Ahsoka and Dooku never even interact! Yes, by the point that Ahsoka is a Padawan Dooku has already walked away from the Jedi, but it’s established in the canon novel Padawan by Kiersten White that Dooku visits the Temple sometimes. Having Dooku and Ahsoka meet, however brief, would have been a great conclusion.
I have a separate blog post about how I think the show could’ve gone, which can be read here. There were angles that could’ve been established and parallels that could’ve been made. It’s a great deal of lost potential.
If Filoni wanted to write several unconnected stories, this could’ve been longer and focused on other Jedi characters, more than just Ahsoka and Dooku. But, ultimately, Tales of the Jedi falls short of what it could’ve been and leaves the viewer wanting.
