Jeez I completely forgot, and I loved Better Caul Saul. Yes he's absolutely up there. The last episode even highlights how legendary of a liar he is.

Yeah now that I think of it, that's a good one for bad liar. Marty showed he's a terrible judge of character and he's so monotone that his truth and lying just all feel like he's detached and you feel he's lying no matter what, or just saying what you want to hear. You don't feel like he's telling you the truth no matter what he says, and that makes him a bad liar.

Best liar could be Littlefinger, Varys, or Lade Elena from Game of Thrones. Or maybe Wendy Byrde from Ozarks. I was actually quite disturbed by how manipulative she was. She nails the emotional side of it. Nearly every issue in the show starting at Season 3 was a result of her ambition and she spins it all so well that even audiences were convinced she wasn't the problem.

Worst liar, no idea dude. That's a tough one
