Nothing Human. A good examination of the merits of using ethically questionable research in the name of saving lives, only slightly let down by the Doctor coming off a little too moralizing in the last scene.
...
Not to mention that the idea of punishing a hologram (the last scene sounded like an execution) for the misdeeds of the person his likeness has been made after, seems a bit stupid.
It's like taking a picture of hitler and then throw darts at it...
Apparently, nothing would have happened if the doctor had just chosen a hologram from another species... which sounds stupid when you think about it.
