There’s at least one big surprise in “Saving Christmas.” I had assumed it would be a 90-minute jeremiad aimed at atheists, Jews, Muslims, and other people who don’t celebrate Christmas exactly the way Kirk Cameron does. Instead, it’s an 80-minute jeremiad aimed at other Christians who don’t celebrate Christmas exactly the way Kirk Cameron does.
It’s not a movie so much as it’s an extended Sunday school sermonette, with Cameron teaching his born-again brother-in-law not to dislike Christmas trees, Santa Claus and gifts, because — as “Saving Christmas” is about to expend a great deal of effort to prove — all of those things celebrate the birth and life of Jesus.
