Intense movie with a plot that seems inevitable. "Van God Los" (which literally means "detached from God/to secede from God" and not "Godforsaken") is loosely based on the infamous "Bende van Venlo" (Venlo Gang) whose mostly youthful members allegedly committed over 250 crimes in 1993 and 1994.
The cold-bloodiness of the murders is acted out very well. It's hard to understand how a 15-year-old privileged dentist's son from the rural Netherlands can commit such crimes. The movie gives a very uncomfortable answer: That there is nothing to understand, that these things just happen because our society is the way it is.
In my opinion, the original title speaks volumes about the tone the movie sets and the answers it tries to give. Whereas "Godforsaken" implies that God "left" us alone, perhaps in disappointment, "to secede from God" means deliberately leaving him behind. Unfortunately, I have no information on the writer's intention here. It befits the film to have to think for yourself about what it means to you. The film will definitely get you thinking for a long while after the credits are over.
