A Merry Friggin' Christmas

I have met one of the most miserable characters in a movie in Mitch Mitchler in A Merry Friggin' Christmas. Notably, the last feature film starring Robin Williams, he plays one disgusting, abusive man. He ends up on a road trip with his son who can't stand him and the film develops a heart. It's not great, but by the end you are with the characters and there is a bit of redemption. It's an OK holiday themed film.
