I would like to give an unbiased review on this. I've seen critic reviews and audience reviews both weigh on either sides and it's hard to understand whether to watch the movie or not.
It's an emo movie with suspense. I would also like to mention that it's a slow paced movie.
If you are a person who wants to watch a movie where you like to be indulged in the movie or if you are a person who likes emotional movies, then go for it. You won't regret it. This is one of those, but you need to have patience.
(My request is that you watch it without any disturbance in a single shot)
My personal review would be: It hit me in a completely different way. Never felt such strong emotions in any of the recent movies.
