Torchwood: Miracle Day... WTF happened to a decent show?

I like British sci-fi shows, and I've been a fan of Torchwood.  I was pretty enthusiastic about the new series, Miracle Day, but...  OMG it's awful!  The pacing of the story arc is painfully slow, and today I tried watching the blond CIA woman tip-toe her way around in the latest episode and I finally gave up on it.  Torchwood used to be cool.  WTF happened?
