That said, the movie's first half has too many protracted talky scenes that only serve to drag out a movie that is at least 30 minutes too long.. And the hysterical final reels descend into splattery madness as Julia, now recovering from an eye operation but forbidden to remove the bandages, finds she is now the hunted rather than the hunter of Sara's supposed killer.
But Rueda's strident engaging performance brings with it enough energy to sustain Julia as the centre of the film throughout.
And though you can see why Del Toro was happy to add his name to the poster, most of this feels less like one of his early films than a modern Spanish spin on the Hitchcock-derived 70s and early 80s films of Brian De Palma.
If they were ever guilty pleasures, then this comes recommended. Best see it before any American remake, or sequels working their way through the rest of Julia's anatomy.
