If you loved Tesis - Faszination des Grauens, try The Others
Eine Brücke zwischen einem Film, den du schon gesehen hast, und einem, den kaum jemand kennt. Das teilen sie, und was der zweite macht, was der erste nicht macht.
Was sie teilen
Both films are directed by Alejandro Amenábar, and they both carry the dread, slow burn mood tags, and they sit in Horror / Thriller territory. If that's the register that drew you to Tesis - Faszination des Grauens, the second film will land in a comparable space — through a different lens.

What The Others is
Darkened mansion on a remote island in autumn with creaking doors. A mother shields her photosensitive children from sunlight. Alejandro Amenábar directs a gothic horror tale.
