Simply terrible plot writing. I feel bad for ewan and hayden having to deal with these directors and producers. They come back to a clearly badly budgeted show, with plot so bad it's way worse than the acolyte. Obiwan's clothes immune to fire, Vader losing to a obiwan who can barely use his lightsaber or the force. A prime darth vader. The second strongest force user and one of the best dualists in the galaxy btw
