Most critics take In Which We Serve as a sincere, well-acted record of a destroyer’s crew and their families, and the wartime reviews are the warmest. The praise clusters on the ensemble: Bernard Miles’s chief petty officer, John Mills and Celia Johnson, and the sense of a classless, credible patriotism running through the cast. Noël Coward’s several credits are generally judged earned, with his character work singled out more often than his direction. Several reviews value the domestic scenes for catching Britain’s 1942 mood and the dangers of the Blitz.
The reservations come from later critics, and they cluster on how the film has aged. Empire credits David Lean’s co-direction with keeping it durable despite Coward’s inexperience, while calling the flashbacks dated. Time Out is the lone negative, finding the class snobbery and stiff-upper-lip attitudes patronising and the film interesting mainly as a social record. The spread is fairly wide, with the 1942 notices well above the modern ones.
