Have you had this experience? All your friends tell you that you must watch this movie, this TV show. It’s hilarious, it’s so romantic, it’s so gripping. It’s a must. Yet if too many people recommend a movie or a show – or a book – too warmly, there is a point at which I turn utterly reluctant to tackle it. This is the reason why I missed Mamma Mia this summer, and why I never watched Buffy the Vampire Slayer. The friend who recommended the latter sang its praises for what felt three hours, and that did it for me.
