Dave Jackson’s review published on Letterboxd:
The Servant is a mean-spirited tumble into madness. Power shifts and warps through manipulation, sex, and dirty dishes. It is brimming with contempt, yet it's also rather funny in its own twisted way. Dirk Bogarde is a great presence, communicating so much in the smallest change of his eyeline. Douglas Slocombe's camera is constantly on the move, adding to the tension of the location. Shadows lurk. Mirrors distort. The film's last act is so extreme and an amazing payoff to the seething slow burn.
