This really killed this weeks episode, which otherwise could have been pretty good. And it had a lot of strikes against it- like the central villian being the source of all myths of Satan. I mean, can we say cheesy? And it's a kinda fragrant British cheese. A Ploughman's Special. Not appetizing. But, y'know, I was gonna let that one slide if they did it well, and uh... they didn't.
Couple this with a string of mediocre episodes that lack the solid storytelling of last season... it's not looking good for the franchise. And because this change in story telling happened with the introduction of David Tennant, I fear that Tennant will be viewed as a poorer Doctor than he is. He's brilliant- the scripts are not.
