I'm not a big fan of the show to be truly honest with you: I find it sluggish, boring, not very imaginative and also to be honest treacherous as a non force wielder called Sabine Wren who isn't even able to pull a small cup of coffee through the force is somehow allowed to carry a lightsaber and be called a padawan.
But that episode however is reaching the heights. It's thrilling, it's fan service, it's full of nostalgia and what a blast to retrieve Hayden as Anakin.
The big highlight is Hayden starring as Anakin/Darth Vader. He's breathing power and wisdom throughout the episode, the epitome of the struggle between the light and the dark side. Having him back on the show is the boost it needed so badly to bring some excitement back.
Too bad it lasted only one episode as I feel with the return of Sabine we're going back to mediocrity.
