I just looked through an episode guide. That’s the episode I was referencing. He was tolerable. I think the animation helps too. He doesn’t look so idiotic. Like you said, he’s also not shown as a complete idiot.
Honestly, watching that episode almost made me forget how much I despise that character. So, props to Dave Filoni, director Justin Ridge & writer Julie Siege for making me hate him a bit less.
Episode 8, The Bombad Jedi episode can be tossed in the garbage can for all I care though, lol. Really bad episode.
