Intriguing interesting movie, unusual in its plot. Everything would have been fine, but the ending turned out to be a bit simple. I thought the answer to everything that happened would be something special, but no — it turned out to be quite banal and simple. Which in principle was to be expected in such a storyline.
And you should not trust the first person you meet, or someone who knocked once at the door. And if the guest knows how to gain credibility, then disaster struck.
