This 2020 Austrian Netflix film is marketed as a horror/mystery/thriller.
There are moments of consequential learning that may be of interest to you and your students. For example, the older son complains that his phone is connecting to the Slovenian network. This could potentially lead to a discussion on technology in various personal uses. This is also a good example of a border town for those who are looking for that variety. The town’s folk speak heavy dialect and there are moments of confusion, as the family speaks more or less Hoch Deutsch. This is done explicitly a few times in the film.
This film has many similarities to the Spiderwick Chronicles. It is appropriate for about the same age range as that film.
