2. Fear Her
Oh man, where do I start? The Doctor and Rose arrive in London 2012, where people are disappearing amidst the Summer Olympics. A few amusing moments with a council employee aside, very little goes right in this episode. Doctor Who has had some pretty questionable child performances in its day, but this one has to be the worst. Chloe is the height of annoying little kids, especially once she's been possessed -- her whispery little voice is like nails on a chalkboard to me. What's worse, it features a ridiculously naff scribble monster, which is made of graphite and can be defeated with your run-of-the-mill eraser. But the real low point of an already terrible episode has to be Ten's run with the Olympic torch. It's pure cheese, as Tennant runs in slow motion to save London and the rest of the world from oblivion. Excuse me while I go vomit rainbows and puppy dogs.
