There’s a theory about Nic Cage’s films, the crazier he is in it, the more entertaining the movie is and boy howdy is he crazy in Mom and Dad. Not just a little crazy or demonic crazy, but the kind of crazy that only Nicolas Cage can do when he’s been directed to be CRAZY. Selma Blair and Anne Winters are great here too, there’s this insane scene at a high school where all the teachers know what’s going on and they’re trying to keep the kids away from the parents and it just does not go well.
This is fucked up enough to suggest parents with small kids not watch it, there’s a few pretty gory scenes that won’t sit well with you. However, if you liked the Purge movies and wished there were more kids getting involved, this may be right up your alley.
