“ ‘S.N.L.’ is too online” is just the latest variation on the accusations of decline that have dogged the show since the sunsetting of its original cast in the late 1970s. But the claim skims over something important about the past 20 years: “S.N.L.” isn’t just hoovering up online culture; it is online culture. I grew up watching the show obsessively, starting in Carvey’s era. The ritual of staying up until 1 a.m., alone in the basement TV room, was formative for me. I have very likely seen every episode made since I was 12. But I haven’t watched one on a Saturday night — in sequence, as it aired — since the early 2010s.
