This is another BBC series that has some crossover with the new Dr. Who, and is in it's 4th season. This year they've opted to go with one big-ass story arc rather than a bunch of little one or two episode stories. While I've always didn't hate it, this season is following a pretty interesting concept and has hooked me deeper with each show. Anyone else watching it? Spoiler BURN OVENS!?!?!? SERIOUSLY!?!?!? Holy Concentration Camp batman!
