JB toed the party line on that, but I prefer to thin Torchwood is not so careless. Yes, they get hurt and sometimes people get killed, but RTD just wanted everything to be doom and gloom for the sake of so called realism, plus he didn't want anyone but Gwen to survive, because that would prove she was so much better than everyone else. Actually, all it proved was that she was too much of a coward to put her own life on the line, she'd sacrifice the world to keep herself safe. The others would risk their lives to save others. Gwen wouldn't. *grumbles*

Sorry sore point with me.
