The Nordheim family is moving from California to a remote farm in Norway. Bill Nordheim (Martin Starr) had inherited the place from his uncle. Carol (Amrita Acharia) is his new wife and stepmother to his children. Teen daughter Nora is angry with the move away from her friends. Young son Lucas discovers an elf infesting the barn.
This is a horror comedy. The horror part is ok although they may have shown the elf a little too soon. I would have kept him in the dark for longer. The comedy is mostly Martin Starr being Martin Starr. Initially, the casting of the kids didn't make sense. I don't see them as Martin Starr's kids. The stepmother part helps a little, but I still don't buy them as Starr's kids. The daughter is a drag until she starts using the bat. There are some fun kills and the multitude of elfs is chaotic fun. In the end, this is not that good, but it has a few fun moments.
