People post on social media how quickly they watched an entire season, not unlike the days when young readers stayed up all night to buy, and then read, each instalment of Harry Potter. Yet when they hear of spending all day in a theatre, the average person will look at you as if you’ve gone mad. Six hours of Peer Gynt, even with intermissions and a dinner break? They react as if you’re a cultural masochist, enduring theatre like some David Blaine stunt.
