If you ever wondered why you should keep struggling in life and never stop trying harder, then you should watch this movie to know what may happen if you ever stopped struggling. You should make your decision out of 2 choices,either to live or to die. Living with drugs,prostitutes and committing suicide is absolutely painful and you are going to feel that pain in the movie.
We should wonder about how does it feel to be alive, not how does it feel to die. The darkness in aimless life, the bad company and overthinking about the past can easily keep you hold in place. And all of that is shown clearly in the well made scenes of that talented actors, in addition to the superb directing and photography that cared a lot about the details of the picture.
The movie has beautiful twists that will keep you alert for the story, but it may get boring at some points so you may need to play it at double speed.
Finally, Remember that "When you are at the bottom,you can only go up".
