Where is the horror ?

Rating: 5/10 (4 June 2016)

I don't know how this movie is classified as Horror ?!!, the only chilling scene is when Sam disappears and that's it ! I enjoyed watching it but I was expecting some really scary moments that would make me jump but NONE !!
I would like to begin with Sam, did the witch just minced him or what? I mean, did she make some youth elixir from him ?!
What killed Caleb ? What happened to him at the "Witch house" ?
How didn't they hear their children screaming when they were locked up with the goats ?
So many mysteries ... This movie should only be classified as Mystery.
