Critics reviews

Its violence is its least predictable part, with the movie zeroing in on sights you didn’t expect and retreating at exactly the moment you expect it to go in for the close-up. In a film thick with doom and dread, nothing is more alive than the camera.

Its ability to keep going and going and going is impressive, but seasoned low-budget-genre director Colin Minihan (Extraterrestrial) grounds the twisty shenanigans in something deeper — or at least gives it the old college try.

If Anderson's performance was as fully imagined as Allen's, then What Keeps You Alive might have attained the emotional dimensions of a robust psychodrama. But Anderson fails to elucidate how Jackie's façade of normalcy overlaps with the truth of her evil, instead playing Jackie as someone governed by an “on” and “off” switch as the plot demands.
