Harry Potter and the whole load of nope. The attack on Katie Bell was both unnecessary and terrifying but mainly because it comes out of nowhere. Walking to Hogwarts from Hogsmede, the trio are behind Katie when it happens. She's suddenly whipped up into the air and when she's being thrown around, she lets out the most horrific scream you've ever heard. Pair that with how wide her mouth goes, the look in her eyes and her hair flying about the place, you have one genuinely scary moment in the Harry Potter series, if not the scariest. But the importance of this attack revolves around Malfoy and his desperation which is making him dangerous with his carelessness and recklessness.
