After the last couple of episodes, I was worried one of the best science-fiction shows ... no wait, one of the best SHOWS on television was going to end with a whimper instead of a bang. They've proven me wrong - YEAH!
Claudia Black is a delightful actress - I suppose it's her stage work that allows her to say more by saying nothing. Her characters moral ambivalence re Adria was palpable. Her lines said she felt nothing while her face and mannerisms said something else entirely.
This is not to say the others weren't firing on all cylinders either. They were all working like a well oiled machine. And, really, isn't this why we watch? We're not here for the weird alien makeup or the other-worldly sets - these characters are friends and we want to keep them close, make sure they're OK.
