This film should appeal to younger teens who love films where other young teens get together to uncover mysterious crime stories as in Scooby-Do and Stranger Things. The Strange House (2020) aka Das schaurige Haus (2020) is a ghost story that takes place as a haunting in the new home this family now lives in the small town.
It starts out with a family who leaves the city for a place in a small town that is more affordable but unaware of a triple murder that had happen 40-years prior. The rumor was that a mother had poisoned her two children and committed suicide. The family is unaware of the history of the home until the children make new friends with other children of similar age in the town.
The woman's handsome boy of the house with his little younger brother meet with a pretty village girl at a summer party. They hit it off well and they meet another child who becomes their nerdy friend. The three set out to unravel the true mystery behind the murders that had taken place back in the early 1980s by investigating clues much like a Scooby-Do or Goose Bumps story.
It's a fun movie for younger teens and tweens. Not very scary. Its more fun seeing them piece together clues to figure out who was actually responsible.
I'll leave it at that. You have to watch it for the big reveal at the end of the show.
