If there ever was a film that did not need a remake, the original "Miracle on 34th Street" was such a film. The original featured a virtually perfect screenplay in which everything works out right against all odds. Above all, it softened the sentimentality with some genuine satire (corporate heads who are so afraid of losing sales that they have to admit that Santa Claus exists)and, above all, with a delightful sense of ambiguity as it leaves open the possibility that Chris really is Santa Claus. The remake just pours on the sentimentality and (spoiler) even changes the ending.
