Still among the most worthwhile of the familiar holiday movies, this classic version of "Miracle on 34th Street" has a combination of cast, story, and production that works well. Maureen O'Hara, young Natalie Wood, and Edmund Gwenn would probably have carried it pretty well by themselves, and they are joined by a very good supporting cast. The screenplay is nicely done, bringing out the fantasy elements of the story without letting it become trite.
Gwenn, who played many solid character roles, gets the chance here to play a role for which he was ideally suited, and it works very well. O'Hara and Wood make a good pair to balance him out. The supporting cast gets some very good moments of their own, especially Gene Lockhart and William Frawley, whose scenes are entertaining while also offering some occasionally pointed commentary.
The style of the production is well-suited to the material, offering an innocently upbeat story without overdoing it on sentimentality. For all that this style of the production and acting are out of fashion, they are able to capture a theme like this in a worthwhile way that is simply not possible with the kind of false "sophistication" that permeates so many present-day movies.
That's not to say that this is some kind of masterpiece, which it is not and did not try to be. Instead, it's a light, enjoyable, positive movie that does make a worthwhile point or two. That kind of feature will always find an appreciative audience somewhere.
