(spoiler) is it normal to react like that?
I think that this movie is underrated.
It builds much atmosphere and tension.
Yes, there are unanswered questions at the end, but do good stories have to answer all your questions? I dont think so...
The only thing that I had problems with was
how they reacted to eachother later on... I mean... if you just saw your wife stabbing her female part... how can you ask her a few minutes later - while you're still not sure if she even is your wife - if that feels good and touch her injured parts with that horny face??
