Most critics are warm towards Room at the Top, and the praise gathers in two places: Jack Clayton’s direction and Simone Signoret’s performance. The earliest reviews call it an adult, literate piece of work with an authentic small-town atmosphere, and later writers agree, treating it as a landmark of British social realism for its frankness about sex, class and ambition. Signoret is singled out repeatedly, for the knowing, loving way she watches Laurence Harvey and for a passion the critics find sophisticated rather than lurid. Freddie Francis’s photography draws its own notice.
The reservations are about age. Several critics say what once caused a scandal now seems tame, and Time Out finds the melodramatic plot does not quite hold up, though it enjoys the film as a 1950s Brief Encounter. Empire notes Harvey’s limitations, and The Guardian treats it as a pungent time capsule rather than a great film. The spread is narrow: nobody dislikes it, and Time Out is the only mixed voice.
