Carl (Toby Jones) lives in a spartan flat decorated in shades of roadkill brown and despair beige. The production design of this slippery psychological thriller is particularly well chosen, seeping under the skin of this middle-aged man whose poisonous relationship with his overbearing mother (Anne Reid, terrific and toxic) has polluted his entire life. Like the view through the kaleidoscope of the title, a cherished remnant of a rare happy memory, the facts of the story are fractured and distorted, seen through the prism of a broken mind.
