Shallows, The (2016; USA; Colour; 86m) ***½ d. Jaume Collet-Serra; w. Anthony Jaswinski; ph. Flavio Martínez Labiano; m. Marco Beltrami. Cast: Blake Lively, Óscar Jaenada, Brett Cullen, Sedona Legge, Janelle Bailey, Angelo Josue Lozano Corzo, José Manuel Trujillo Salas, Diego Espejel, Pablo Calva. A young surfer becomes trapped off shore when a great white shark strays into the waters. Tense, bare bones thriller with an excellent performance from Lively in a demanding role. Avoids most of the conventions of the deadly shark attack genre for the majority of its nerve-jangling running time until the very end, when Hollywood conventions kick in.
