I would say I like dramatic thrillers a lot - particularly when events are happening in a real life, not in someone's head. If a confrontation arises between main personalities, it provides additional value to the film. In Mørke, the respective atmosphere and preconditions are capably created, but the main opposition is not equal: Jacob (vigorously performed by Nicolaj Lie Kaas, at least 1 additional point from me due to him) is much stronger and versatile character than "soft" Anker (Nicolas Bro) and the reasons for the latter's actions could have been different than appeared in the end (with a decent twist, however). Or perhaps I am more interested in materially motivated actions than spiritually.
The film is undoubtedly for you if uneasiness, gloom and doubts throughout the film are important and long moving scenes do not become boring.
