This show asks more 'morality' questions than anything I've ever seen on the tube...Euthanasia and such, just this last go 'round...In which circumstances is 'murder' permissible...If one person's existence jeopardizes the continued existence of the group, should that person be terminated?...If someone is suffering extensibly, can they be put out of their misery?...Wow, this is even heavier subject matter than that 'very special episode' of Diff'rent Strokes...
