This definitely is one of Shirley's three or four best, mostly because she is not required to perform a tearful treacly scene as in some other films, those which tug at your heart but later seem somewhat embarrassing. This is one in which she comes across as a young actress, and not simply as a personality. The musical numbers are unusually effective; probably because they are shared with Alice Faye and Jack Haley and not strictly solo. (You have to smile over the final number, when the military band number, well done though it is, is done with full costumes and choreography, even though the performance is taking place over a radio hookup.) Shirley conveys an innocence and trustfulness and joy in life which is a universe removed from portrayals of children in contemporary film and TV. One more remark: I was truly surprised to see the appearance of a pedophile in a film of that era, and to see Jack Haley confronting and fighting him as he is about to lead Shirley away from the apartment house.
