Even if the critical reactions have been mixed, Italian films have proven much stronger than usual at this year’s Venice Film Festival, with a notable resurgence of genre filmmaking in the likes of Adagio and Enea. Ironically, Matteo Garrone, the one local director in the selection whose actual stock in trade is genre of all stripes — gangster realism (Gomorrah, Dogman), satirical comedy (Reality), and baroque fantasy (Tale of Tales) — arrived this year with a blisteringly topical drama that might be his most traditional, and best, yet.
