This thriller movie could've been better. The casts were able to execute their roles outstandingly but the storyline is too lacking. Too much complications just to express that spending time with your family is way better than spending time on your work.

For most parts, more than the curiosity about what's happening or what's going next, confusion prevails. Usually this kind of movie is slow burn where the details are given on the first part and it will unfold slowly towards the end giving that 'wow factor' but this one did not. It kept me hoping it will get better towards the end but it didn't. It left more questions than answers. On a positive note though, the music was able to set the mood of the movie giving out that creepy and eerie feeling.

The main lead Song JiHyo and Kim MuYeol executed their roles outstandingly. They were able to make their characters stand out by giving that mysterious vibes that fits perfectly on the theme of the movie. It such a shame that storyline didn't do well to match up their superb acting.

I personally watched this because of Song JiHyo and it really makes me sad because JiHyo is such a versatile actress and I really love to see her portray different roles but the storyline always falls short. No matter how good of an actress she is it's impossible to save a bad writing.

I know most people who knows Forgotten also felt this has the same vibes but for me, I think Forgotten is a better movie. However, for a fan of JiHyo like me, this is still a decent movie to watch and we get to see JiHyo on a different role.
