Nicholas are said to arrive on the evening of December 5 (Krampusnacht; Krampus Night ). While St. Nicholas rewards nice children by leaving presents, Krampus beats those who are naughty with branches and sticks. In some cases, he is said to eat them or take them to hell.

Overall Krampus is a scary and creepy horror film. However, there are some redeeming qualities and noteworthy messages for kids. Parents need to be aware of the excessive violence and crude language throughout the film. Depending on the child, Krampus is appropriate for kids ages 13 and up.
