In case you're wondering, no, this is not a movie about a haunting, possession, zombie or another 'Pet Sematary'. There is a very subtle scene that edges more towards an alien movie, but its also not that kind of movie.
'Daddy's Head' revolves around the loss of a loved one. In this case, young Isaac is longing for his father, James, who passed away after a car accident. James recently got married to Laura, now Isaac's stepmother. When James dies, Laura considers sending Isaac to an orphanage, because she is convinced Isaac "hates" her. The two of them don't really get along, and is aggravated by James' absence.
When something starts lurking around the house at night, Isaac is convinced it is his Dad, who has come back for him, although he looks different - he has the same head, but a different body. The 'creature' is creepy and the sound effects are very good and scary.
The characters are well set up to make their actions believable. Rupert Turnbull delivers a strong performance as Isaac, and we root for him even though we know he is in the wrong. And then there's Laura, who not only has to come to terms with the loss of her husband, but also having to deal with Isaac. She confides in her friend, Lucas, which causes more friction between them. Apart from the supernatural horror, this is also a character study.
Over-analyzing the film will result in too many questions, like why the creature chose Isaac, how did he manage to resemble James, and what did it stand to gain by misleading a young boy? Rather just sit back, and enjoy the film for the creepy ride and unpredictability, with jump scares galore!
