After a moderate upturn in quality last week, tonight was business as usual. The sad thing about Doctor Who these days is that an episode can contain great ideas, look superb, be full of agreeable political commentary, and yet still be utter shite. Tonight's story had a solid if well-worn story at heart, but was let down by mad pacing, underdeveloped characters, and an environmental message so clumsily delivered that it left me winded.
