I finished watching Tales of the Jedi on Disney+. It's a series of animated shorts from the Star Wars prequel era. The series provides more detail about both Ahsoka Tano and Count Dooku.
I really liked this series. I breezed through it quickly.
I loved Star Wars: The Clone Wars (and Star Wars Rebels). Tales of the Jedi fit right in.
I've actually started watching Star Wars: The Clone Wars again because I liked it so much.
Ahsoka Tano may be my favorite Star Wars character. She was a little silly in the beginning. Through the various TV shows and even in the book (Star Wars: Ahsoka), she really grew into her character. I'm looking forward to the live-action show Ahsoka coming out next year.
If you liked Star Wars: The Clone Wars and Star Wars Rebels check out this series. I don't think you'll be disappointed. Even if you are, the shows are incredibly short.
