Cert 18 Stars 3

This creepy psychological horror is at its strongest when allowing Kevin Bacon and Amanda Seyfried to bicker and simmer in a fractious mood of marital mistrust and sexual insecurity, but loses its menacing allure when they’re forced apart by a script which can’t disguise its intentions.

This is surprising as director David Koepp’s writing pedigree includes blockbusters such as Jurassic Park, Mission: Impossible and Spider-Man, however he establishes a strong look and tone, and gives us for the first half at least plenty to ponder as he sends his stars to a remote Welsh house for a nightmare holiday.
