Everybody mocks Daleks but they're somehow astonishingly scary. I put this down to the way they have no faces - you just don't know their thoughts. Also, they seem to have phlegm in their throats, which is no doubt because they've no faces to spit it out with. I like the flashing lights on top of their heads, they look like menacing versions of those vans laying out cones on motorways at night.
