No filler just killer!!! You got a really great storyline for a show with 6 short episodes. The action is just great, amazing animation and writing. Dave Filoni really outdone himself with this mini-show. Despite the short screentime the story that is presented throughout the 6 episodes adds a lot to the star wars franchise. This show completes the backround of Ahsoka and Dooku's backstory really well. Although i would have loved to see longer episodes the content we got is just great. I had high expectations for this show and i was still blown away by how good the 2 story arcs were. I had a great time watching this and i highly recommend it.
