I'll be an outlier and say that if Torchwood had ever given off the impression that any of its writers had so much at glanced at another script from the series it wouldn't have been Torchwood, because part of the funky charm is that the team are so crap at what they do, but that said, CoE didn't even manage internal consistency within itself, which is Bad for a group of 5 episodes supposedly structured as a single story. I can perhaps spot them some of the larger Whoniverse continuity issues for the sake of clarity with a wider BBC1 audience who might not be as familiar with the larger context as we are, but they could at the very least have paid more attention to whether their continuing argument was holding together over the 5 nights...
