The opening mashup is as good as people said, then between each ad break they pick a particular focus: Lonely Island, hip hop, star-making performances, the dangers(?) of live television. They take pains to tell us what an honor it is to play such an important show, how vital is SNL to our culture, and if you don’t agree with this premise then it all starts to feel hollowly self-promotional, but there’s sure some good music along the way.
