SGU is making it extremely difficult for me to play "Let's pretend!" A communication system that puts shipboard people back in their lives on earth? Not holograms, because they interact with family members, etc. And this communication system works across billions of lightyears of space?? Oh, come on! Phooey.
Sanctuary, on the other hand, had another pretty good episode. It had a magical ending, restoring the world to the way it was before the plague hit. But you accept an impossible ending on this show, because it's fantasy. SGU is mixing fantasy with SF and doesn't seem to recognize the difference.
