When I was younger, I found supernatural stories extremely scary. Now, as I grew older, home intrusion is far more terrifying for me; it's realistic.

The movie drops us into the plot from both the introduction scene and the first scene with our female lead. We have no time to adjust to the creepiness of it. The anxious feeling increases with every scene shot in that small apartment, making the viewer feel paranoid and claustrophobic.

Kyung Min is not exactly the smartest character ever. She makes many mistakes and jumps to conclusions too fast, but wouldn't that make her more relatable and realistic? That said, the lack of either fight or flight response in some scenes was quite frustrating to watch.

My biggest complain character wise: how lazy and dumb the detective was. The conclusions he came up with made no sense taking into consideration circumstances.

Plot wise, there were few moments that surprised me, small twists I did not see coming. I kept questioning and guessing who the mysterious man is, and always failed with my predictions, every character fitted the creep quite well.

Overall, it was quite an enjoyable movie. The pacing was good, though some work related scenes were not necessary since they did not bring anything new either character or plot wise. Adding some more sequences of the man "intruding" would be better, since these were the most atmospheric and well shot.
