Most critics take to Mrs. Miniver warmly, and the praise clusters around two things: William Wyler’s direction and Greer Garson in the title role. The wartime reviews are the warmest, admiring the restraint with which the film shows an ordinary English family living through the bombing, and more than one singles out Walter Pidgeon as the husband. Later critics are cooler but still mostly kind, crediting the air-raid sequence and the picture of Home Front life, and noting that the film avoids the worst of flag-waving.
The reservations are about sentiment and length. Two reviews find it long, and Time Out calls it a well-dressed soap opera in which everyone is frightfully nice. The spread is wide: the lone dissenter, Collider, finds it dated, earnest and dull, and argues the story reflects wartime necessity rather than anything lasting. The further a review sits from 1942, the less it likes the film.
