I wanted to recommend a couple of amazing video essays/deep dives done by loreandlight (that's her name on twitter and youtube) that are analyzing characters played by our lovely Michael!
The first is about Leland Townsend! It's amazingly detailed, it analyzes his role in the show, how his backstory informs his current endeavors and personality, it touches on his schemes, blasphemies, relationships with others, it answers any questions the show might have left open and unravels any mysteries about him, it explains things well and it even discusses the fandom and how the character commands such loyalty! There's a lot more to it, it's wonderful. It's HERE!
The second video is about Dr. Siggi Wilzig from 'Fallout'! It's an exploration of his morality and how the show is making it clear that he's a good guy. It discusses the narrative itself, the acting, real life historical connections and more. Watch HERE!
