That's not a bad synopsis. The series pushed hard on what the limits of moral behavior are. I like books, movies and TV shows that push the limits of moral behavior. I don't mean appetitive limits. That's prurience, a shallow substitute.

It asks a question theologians and philosophers have puzzled over since written history: What serves the greater good?

So yeah, I liked the show.

Now about Masterpiece Theatre, how would you reconcile my appreciation of both? What is it about MT that would appeal to that envelope pushing predilection?

Or NOVA, of which I am a huge fan?

Most people have more dimensions than the observer can or wants to see.
