Even though this story is different from what you would expect, there are no actors dressed in cheap-looking cat costumes, the writer never lets go of the "Cat" element. It's the theme that intertwines the story together. Pretty much every scene has a cat or cat-like element in it. But you don't feel overwhelmed by cats though, like you've just entered a woman's apartment and 30 cats swarm around you. There are a lot of hints thrown at the audience to give them a heads up that there is something suspicious about Irena, the main character. It's intensified by the fact that Oliver, Irena’s love interest, is oblivious to the signs which are omens of potential evil. The most famous scene is the one when Irena's jealousy overcomes her and she prepares to pounce on Alice as she swims alone in a hotel pool. Lots of writing here to set the mood, build up the tension. I noticed a heavy amount of text in order to make sure the important scenes convey what they need to.
What's really scary here? The fact that this nubile, delicate young woman can entice an everyday, normal, nice guy into marriage when her true evil, which she has tried very hard to surpress, bubbles to the surface. And the idea of being cursed and living your curse without ever having a hope to be able to break it, forever being trapped by extenuating circumstances. The idea that a basic human emotion, like jealousy, could transform oneself into a monster!
