Excellent discussion everyone. I won't try to throw my two cents in (because, hey, I'm not a very good debater) except to say that I agree with DevilEyes
and Nerys Ghemor
about abandoning all universal moral values. Maybe that's because I'm a theist and like Deranged Nasat
said, I "perceive the universe as having intrinsic ethical qualities."
My biggest issue with the B-plot is it felt really out of place in this episode. It's like they finished writing it and then they realized they were about ten minutes short, so they threw some random crap in there to fill the extra time.
Which is pretty much what Ron Moore said about the episode - it sounded good in theory to have a light B-plot to counterbalance the intense A-plot, but in practice it was a huge mistake.
