2) Blink
This is possibly the most pant-shittingly terrifying episodes of television EVER! I was 9 years old when I watched this and my little brother was 6, and the pair of us were scared out of our wits. I seem to remember him running upstairs screaming for our Mum, and neither of us would go upstairs in the dark on our own for at least three weeks after, for fear that the Weeping Angels might be waiting for us. Honestly, it still scares me now. Whenever I’m home alone and I hear a noise, I have an irrational fear that a Weeping Angel is going to burst through the door at any moment. And the whole ‘wibbly-wobbly timey-wimey’ element of the episode is absolutely genius, and adds to the suspense and the terror during the crescendo of the episode. Show this one to your kids, and they’ll have nightmares until they’re 19.
