If you loved El cuchillo en el agua, try Repulsión
Un puente entre una película que ya has visto y una que casi nadie ha cruzado. Esto es lo que comparten, y lo que la segunda hace que la primera no hace.
Lo que comparten

What Repulsión is
London flat, summer heat, a ticking clock. A sister departs, a roommate remains, alone with her fears. Polanski shoots the collapse of a fragile mind.
