Hallmark Channel is the home of holiday cheer thanks to its annual "Countdown to Christmas" programming - which just keeps getting bigger and better. Every year, fans are treated to a slew of feel-good holiday movies starring Lacey Chabert, Andrew Walker and more beloved actors. While the stories showcased are different, there are a lot of themes that are present throughout every film, including love, family and Christmas spirit. So what makes those movies great? Fake snow, tree lightings and more cliché moments that viewers and Us can't get enough of, obviously.
