Successful Horror

Good "horror movies" are in my opinion a real rarity. This was after a long time again a you could watch without hesitation and even can recommend. It not a classic horror film and it also flows virtually no blood, but for me these are no criteria for a good horror film.
This film makes the exchange between fiction and reality, which is triggered by a mysterious game.
I want to spoil anyone the film pass, I will not go further into the plot.
But from me a clear recommendation.
