I have many least favorite movie/tv tropes tied for most annoying. One of them is how groups that survive the apocalypse always seem to be comprised of only useful members, with no crossover skills. Always someone good at shooting long distance, someone good at hand to hand combat, an electrician, an amazing driver, a medical doctor, someone who works for intelligence (knows the right people, knows where to go, knows a safe house, etc.), and an all purpose scientist who knows everything from botany to nuclear physics. It's never like a window washer, a hand model, a bank teller, and a hairdresser.
