A film about Santa Claus relying on his violent past to save a young girl from kidnappers? Seems like a total home run. Violent Night has some clever Santa-themed kills (though the violence is blunted by CGI blood). But the movie’s best aspects (e.g., Santa’s violent Viking past, David Harbour’s performance) get diluted by references and similarities to other classic Christmas-themed movies (e.g., Home Alone, Die Hard, The Ref). Which is a shame, because this has “cult hit” written all over it.
