Das Tal der toten Mädchen

I accidentally started with part 3. It turned out to be a trilogy of which this is part one. I also thought this was a Spanish movie, but the language sounded like some weird dialect I never heard before, after about 30 minutes it was revealed to be Basque (part of Spain) and that it apparently is a separate, somewhat similar language.

The movie is a classic detective: girls get murdered in a serial killer way, inspector Salazar is the lead agent in charge starts solving the crime clue by clue. The way it plays out was somewhat weird though. It is current time but they talk about a mythical creature (like Bigfoot). At first I thought it was meant to be funny but it was quite serious. Then there's a next clue that comes from reading tarot cards... Some things don't seem to have logic or just come out of the blue, or ominous music starts that warns the viewer something is about to happen but what happens has nothing to do with the story and is basically unneeded. I stopped rewinding after a few such instances and just went with it. The ending makes sense though, nothing mythical about it, just plain old detective work to find the twisted culprit.

You need to see the trilogy for everything to become clear. The ending of 'El guardian invisible' is the announcement of part two.
