Director Luca Guadagnino is keeping busy these days. Last spring saw the release of “Challengers,” which managed to find an audience for its sexually charged understanding of friendship, rivalry, and lust. He returns to screens in “Queer,” taking on another challenge of sensuality and psychological unrest, attempting to bring the world of William S. Burroughs to life with screenwriter Justin Kuritzkes. The adaptation material is a 1985 novella from the author, and 160 pages is turned into a 137-minute-long picture that surveys special feelings and relationships while the characters kill time in Mexico during the 1950s. Guadagnino typically makes specialized features for certain viewers, and he doesn’t deviate from his formula in “Queer,” working to extend what little story there is here, filling the offering with dreamlike visuals and pregnant pauses.
