9/10
In Fatman, we get a sort of semi-grounded and semi-realistic take on Santa Claus (played by Mel Gibson), in which he has become grumpy and is losing his faith in humanity. Meanwhile, a particularly nasty child (played by Good Boys' Chance Hurstfield) has hired a hitman (Walton Goggins) because he got coal in his stocking. This is one of the most original films I've seen in a while.
What's so remarkable about Fatman is that it's able to balance dark comedy and human drama in a story about Santa Claus. The whole thing weirdly manages to fit Chris as he's called in this into the real world. Instead of a traditional, classic Santa's workshop and village we get a farm with a factory that looks like an actual factory. Directors and screenwriters Eshom and Ian Nelms do an excellent job of directing. The majority of Fatman is the buildup to the hit on Santa. The movie is rife with exposition and characterization, but I never got bored because the directors do such a great job of pacing everything and switching between the various cast members. It doesn't hurt that the dialogue is great.
Great cast across the board. Mel Gibson does an excellent job portraying an Old Man Logan/Wolverine style of Santa. He manages to still imbue the traditional aspect of Santa's generosity toward his fellow man beneath his tired exterior. (I'm complimenting the performance, not the person). However, it is Goggins who steals the show. His hitman (referred to as Skinny Man in the credits) is a wonderful combo of quirkiness, charisma, intelligence, and cold-blooded efficiency. The movie is almost as much his as it is Santa's.
This was clearly filmed on a budget, but the Nelms did a great job with what they had. A lot of the locations they picked looked pretty good, and they did a surprisingly good job of the more fantastical elements of Santa. (No reindeer, though, sorry.)
I highly recommend this unless you're not a fan of R rated films in general. (Yeah, in case the hitman didn't tip you off, this isn't your traditional Christmas family fare.) If you're looking for something else, than this is for you. It's just a hell of a well made film.
