It's not often that I write a review. Not even for movies i've seen multiple times. This turned out to be a movie that screams  "write a review for me!" It's that good.
If you're into the suspense thriller genre that is...
When you go by the summary of the movie, you might think that it's just an abduction/family movie. I personally thought something down the lines of someone getting plastic surgery to invade the family and do something... I don't know. I'm happy it wasn't what I had in mind. It was so much better.

At the first half of the movie, you're slowly sucked into the story and the events happening to/around Jin Seok, and you think you sort of get what's happening or what is about to happen and then the second half of the movie kicks you all the way back. What you thought was happening, isn't happening at all. It surprised and intrigued me even further. Although, to be fair, when the second half of the movie started and they started to explain the events to you, I got bored for a few minutes. Gone was the suspense and the mystery. Just to start back up again. AND kick you in the gut with the ending. It's hard not to give any spoilers.

Anyways, before I digress. If you look closely in the first half, you get a few hints here and there that will give you an "Ah-ha!" moment later on, if you saw them. I didn't think much of them at first, until i went back to look at it again. There were a few major "Ah-Ha!" moments for me. And even though I didn't expect it at first, I cried during the last 20 minutes of the film. So yes, I would definitely recommend watching this.
