I've been saving this one for last, because it's decidedly not cheesy.
If you're looking for a plain old Christmas pageant on screen, you're going to be caught a bit off-guard, especially by the dialogue. This isn't some hokey Hollywood bastardization of the Christmas story. This is modeled after the medieval Nativity plays.
The archaic, rhymed dialogue and the lighting give this an overall tone of reverence and age befitting to such a holy narrative. Notably, the commercials are only at the beginning and end; the play is uninterrupted.
Such a solemn, joyful treatment of Christmas on TV is impossible to imagine today. I doubt it was commonplace even in the early 1950s. If you've watched none of my Cheesy Christmas Movie series, watch this and leave me your thoughts in the comments.
