This will be a really short to the point review.
For me the synopsis was what caught my attention. I haven't watched the original movie, so it was a fresh story for me.
I loved the story. How the tension was created and the climax was build up. Especially the ending. For me that made the movie 10 times better.
I liked the cast. The characters were portrayed nicely, enough for you to get caught up in their moments.

The music helped created the atmosphere, the tension that was needed for the climax. I like how they used different types of songs -not their ost- to show a new light to the character. Really smart.

Will rewatch this. And i highly recommend it, if you enjoy drama. It has a lot of drama.

An overall good movie.
