This is a movie about life, about human nature, about drugs, love, poverty, temptation. Though Paco (a young man) is the central character of the movie, the other characters complete the picture - rehabilitating from drugs but more important rehabilitating as persons.
I got several ideas from this movie: in the end you have to accept things as they are, you have to accept responsibility for your life if you want to go forward, we are not perfect - we are just humans, you can't escape from addictions but rather you can replace them with something good, the line between good and bad is not always so clear.
The movie it's a drama, there are lots of sad scenes but what was important for me is that the end lives you with hope. There are some sex scenes in the movie and they fit perfectly in the story.
Why should you see this movie? You don't have to. But if you encounter problems in your daily life (as we usually all do) it may help to see that you are not alone and also that you may reach a "floating" level.
