If you want to watch this movie....
...don't watch the trailer, unless you've seen it already. Don't read any of the reviews fully. Don't even read the synopsis. All you need to know is the genre: drama/thriller.
I've watched it yesterday, without any expectations, or knowledge about it. Perhaps that's the reason I found it fantastic. But it's easy to get disappointed if you first read a lot of praise about it, or get spoiled by the synopsis.
