Kehinde Wiley is in danger of overexposure at this point, but his show of four grand new paintings (and a few oldies) at Deitch closes this Saturday and we think you should see it. As is usually the case with Wiley, the paintings are flashy and immaculate, depicting young African-American men as fallen urban warriors. But the monumental scale of the works — they're like surfboards for giants — gives the show a more somber feel than we're used to from the artist.
