Despite its sinking into insignificance upon initial release, the eventual ascendency of It’s a Wonderful Life was always almost inevitable. For one thing, it stars Jimmy Stewart. For another, like all the greatest Christmas literature, it has an undercurrent of darkness to it. Like A Christmas Carol or A Charlie Brown Christmas, it deals with the death of human hopes as much as their renewal. And, most importantly, its emotional punch grows, not diminishes, with rewatching over the years.
