Not very sinister (A little spoiler alert)

Rating: 3/10 (10 October 2015)

I am not a fan of the Horror genre, because I take the films very seriously and I end up pointing out all of the mistakes and what they would have done better. I watched this film only because my friend asked me to. I didn't have any expectations and I still hated it.
Basically, some diabolic medieval spirit who looks like a member of Slipknot, makes children kill their families. Ethan Hawke plays a Stephen King-esque author, who wants to resolve the mystery around the crimes, hoping that he will write a bestseller horror novel. This is the only interesting part.
More on the matter, the action is incredibly slow, nothing spectacular really happens, besides some random appearances of cartoon-ish children ghosts. And of course, the classic dumb reactions of the horror films characters were habitual: like going alone in the dark to find out from where that strange sound came from.
And what's with the title? It's so meta and it feels like they didn't even try to come up with a cool one. Aren't horror films supposed to be sinister? Let's be thankful they didn't simply and solely name it "Horror".
