Only episode I ever had a sorta dislike for was the one in season one with Anthony Stewart Head in.
I never understood why Duncan would put his friends at risk, and be willing to kill people to defend a rapist.
Maybe at the begining he might have defended him, when there was some doubt, but even after he knew the guy raped the other immortals adopted daughter, he still kept killing the human mercenaries and had a sword fight with the immortal.
