This movie is one of the good ones, I really enjoyed it, the chemistry between the main characters was amazing, and even though i'm reading the novel I think they portrayed the relationship of the youths really well.
One of the things that really attracted me in this movie was the details, the male character's place, clothes, hair and injuries really described his life, and his pain, he didn't look like a bad person even though he had all these tattoos, instead he looked lost, and dark.
As for the female character, she was portrayed in the novel as a stutterer and she acted like a child, but in the movie she's like one of these people, who knew a lot but kept it to herself.
I liked the first half of the movie better, the second half fell off for me, but overall, it was worth watching.
