Plot hole-ish thingy
Ok, so I loved this movie (and Olga Fedori is sa-mokin' hot!) but I did notice one thing that apparently no one else has:
All the while that Lena was tied up, the chain link looking things on her bonds could have easily been undone. They are not even meant to be secure which is evident when she finally sees that the one has come unscrewed and she takes them off. The thing is, she could have unscrewed them anytime. The prop department should have used real (or real looking) chain links instead of obviously removable ones.
I don't love her.. She kicked me in the face!!
