The reviews are unanimously positive, with praise centred on Hitchcock’s brisk direction and the ease with which the chase thriller accommodates romantic comedy. Critics repeatedly single out the handcuffed courtship and crofter’s cottage sequence, while Robert Donat’s performance earns approval for moving between humour and fear. His pairing with Madeleine Carroll is another recurring strength. Most critics also stress the film’s influence, finding the foundations of Hitchcock’s later thrillers in its wrong-man story, resourceful set pieces and mixture of suspense and wit.
Reservations are minor and the spread is narrow. The Guardian finds the opening creaky, while Eye for Film notes dated accents and dialogue delivery; neither considers these faults a serious obstacle to enjoyment. Differences are chiefly matters of emphasis: alongside the widespread appreciation of the entertainment, Slant Magazine draws attention to alienation and doubt beneath the charming spy adventure.
