Once again, Peter Dinklage just...nails it (well, except for his accent, which has always been a bit iffy). One other thing i've found really interesting with the show is how they've made Stannis a LOT more personable and likeable.
I kind of lost that likable aspect the moment he tossed the leaches into the fire. Geoffrey? Sure. Balon Greyjoy? Absolutely. Rob Stark? Ugh. That's just dumb. He seriously needs that "power resides" riddle lesson.
