I was not very impressed with this one. If you like overbearing and relentless music to tell you that SOMETHING INTENSE AND SUSPENSEFUL IS HAPPENING RIGHT NOW for 90% of the movie even though nothing is really happening, then this is your movie.
Just because this is Swedish, that is no reason it should garner any comparisons to Let The Right One In.
It's reasonably well done, but overly long that they tried to make super intriguing and it comes off way too hollywood and ends up backfiring IMO because all the "intense" parts are just like crying wolf because it's actually boring (and I have ENORMOUS tolerance and a preference actually for slow movie. This would have been BETTER if they had just let this be a calm and slow detective-movie but instead they tried to fake it with stupid relentless music and relentless seriousness). And is there anyone in this movie that isn't getting raped? I mean really? Incestuous Nazi torture and rape? What else can we throw in there? Oh wait, I'm forgetting, it's incestuous Nazi torture and child rape. Yeah that'll do for a good villain. Oh wait no, I forgot a couple more, let's make it racist antisemitic incestuous Nazi corporate baron torture and child rape and religious ritual murder against women. I think that covers it. Oh wait no that's not enough, let's throw in some other crazy rapist abusers for good measure just to drive home the point. Which is what, actually? You shouldn't be a Nazi that tortures and abuses your own children or rape your sister or anally rape people you're supposed to be helping or extort people for sex, or just generally be a raving psycopath? OKAY I GET IT ALREADY. It says something when the most rewarding part of the film is watching somebody get a dildo *kicked* violently into their anus.
Just not really my cup of tea, and really not a very interesting who-done-it. I got really tired of the endless time devoted to INTENSE SUSPENSEFUL STRING INSTRUMENTS MUSIC while people are checking their email, walking around, looking at pictures, etc. I felt like I was being treated like a moron the whole movie. "OMG LETS LOOK AT THIS PICTURE!!! Look! A face!! DUN DUN DUNNNNNN!!!!!!" or "OMG I'M TYPING SOMETHING IN A WORD PROCESSOR!!!! CRIKEYS!!! WHAT TENSION!!!!!!" Or, oh wait, you're running around alone in the woods WITH MORE TENSION MUSIC, I don't expect anything to HAPPEN, I'll pretend to be SURPRISED!!
C+ if you can stand to sit through it.
