From the TV serials, I gathered the most interesting part of Sword Stained with Royal Blood to be the backstory with Golden Snake Gentleman but as I grew up I was weirded out by the rest of the story...

that Golden Snake's love interest seemed to have Stockholm Syndrome when he kidnapped her. Got more creepy when her younger sister grew up to look exactly like her and fall in love with brother in law (who reportedly killed her sister).
Yuen Tsing Tze was more interesting and smart as a child. Then he follows Li Zhizeng to overthrow Ming and his love life is a mess. My strongest impression is Gordon Lam and Charmaine Sze gazing at each other for 7 minute stretches in the TVB adaptation. Seriously? Then him running off with the orphaned girl because he promised his master to take care of her and dumping the princess.
