“Kill Your Friends,” a dark satire of the late-’90s music industry, is amusingly slick and biting for a while. Nicholas Hoult stars as a successful and handsome but secretly homicidal A&R executive at a London record label. But comparisons to “American Psycho” are inevitable, and “Kill Your Friends” doesn’t measure up favorably. The soundtrack is pretty great, though. My RogerEbert.com review.
