Watching Kanye West’s “Bound 2” is about as joyous as romping through a stock photography website. The generic sprawling sunsets, mountain vistas, and gradient backgrounds are airless. Our two protagonists are large as gods, with Kim Kardashian reclining in the buff—though her nipples are airbrushed—playing a human hood ornament atop Kanye West’s motorcycle. These two celebrities, and a growing cadre of other stars, are unlike their predecessors; they like art, and they’re getting treated like artists.
