I remember Callum Keith Rennie as Second Henchman from the Left in X-Files, that's how good he is. You're right, whenever I see him, I know that the character has a full backstory, reasoning for his actions, and you can see all of that in his eyes.
But...MacLeod had that trashy douchey ponytail and Methos was cynically hot. I loved the Chivalry episode and it's on my list of, "TV episodes to rewatch when I'm home sick." I'll check Evening at Joe's out.
Count me as someone who thinks the constant trashing of a show on an active message board is just ruining it for everyone else. I loved S4-7 of Game of Thrones, and the first 3.5 episodes of S8, but talk about a toxic fandom. Everyone had their favs, and I was firmly on the side of hot Jaime Lannister, but the fighting between Jon and Dany fans made me want to run to anywhere I could talk about the show but not talk about those two.
Also...spoiling history, when Rome was on, I might have mentioned something about Brutus being key in the future slaying of Caesar and was told, "No, not Brutus, he isn't that kind of guy." Bwhahah.
