Eugene Koltyarenko’s “Spree,” a thriller about rideshare driver Kurt Kunkle (Joe Keery), whose quest for live-stream viewers takes on an increasingly sociopathic bent, hybridizes two strains of movies born of the Internet age. The film is pitched between a “screenlife” movie like “Unfriended” or “Searching” and a small but mighty canon of emerging dark comedies about “extremely online” sociopaths that includes “Ingrid Goes West” and “Assassination Nation.”
