The weather’s fabulous but there’s nothing new under the sun in “Formentera,” the sophomore outing of Teuton helmer Ann-Kristin Reyels (“Hounds”). Set on the titular Mediterranean island, pic follows a Danish-German couple that have left their child at home so they can have some time alone — and boy, do they need it. But instead of exploring the psychological damage that routine can wreak on relationships, Reyels saddles her protags with a sub-Antonioni mystery plot that distracts from rather than facilitates access to the characters’ emotions. Beyond German-lingo territories, Euro cable and some fests will bite.
Ben (ubiquitous Danish thesp Thure Lindhardt, “Keep the Lights On”) and Nina (Sabine Timoteo) stay with some superannuated hippies presided over by a friend (Geoffrey Layton) of Ben’s dad. They’re joined by pretty young thing Mara (Vicky Krieps), who’s awfully flirty with Ben; this sidelines the jealous Nina before Mara disappears in the waves. Swiss actress Timoteo (“Brownian Movement”) is best in show, while Lindhardt has a tendency to grimace. Tech credits are garden-variety, with the exception of a minutes-long shot in which the two finally face the truth.
