“Whiplash” makes a possesion out of percussion
What does possession look like? Does it entail crawling up walls, becoming a vessel for Satan and vomiting up green slime as in “The Exorcist” (1973)? Or is it subtler, with glazed, absent eyes, isolation and monomania? If “The Exorcist” were set at the Juilliard School, the result would be “Whiplash” (2014). Director Damien Chazelle wrote the screenplay to “The Last Exorcism Part II” (2013), and brings his demonic expertise to this compact gem of perfection.
