It is a bit too easy made without a real understanding of the story. Could be evolved more. Pity it could be so much more, it does not stretch the time you got entertained all the time.

More a movie to spend time not a movie to spend quality time.

Not great not bad sums it up perfectly. The problem is everyone is an expert and if it has even a single jump scare the pseudo critics and film school wannabes immediately reject the movie. It's maddening that you see so many jerks who clearly have no control over aspects of their lives that they wish they had they turn into professional critics to take out their frustrations on a movie. It's a horror movie just like every horror movie before it the same weaknesses and strengths but for some reason horror movies more than any other genre get torn apart in ways that the tiny picked nits are seized like doughnuts at the first weight watchers meeting. I watch horror movies almost exclusively and being stuck at home I probably watch 20 plus a week this doesn't make me anymore of an expert than those I'm ripping with this but it makes it easier to spot an unreasonably critical attack.

At the beggining I thought it could be a good movie even, but it was not. Actually the story is not so exciting at all, and not even making any sense yo be honest. Someone found an old warehouse and thought it could be a good place for a horror, then went home, ate too much dinner, then fell asleep, had a disturbing dream and the next morning quickly wrote something around it, mixing old horror stories. That is how these stories always born. But to be honest Stephen King was doing it much more better (even after some pretty lame movies they made from his books) I don't even know why I'm trying to find a good horror story or even a movie nowadays. They all used, and it seems these days anyone can make a movie, who have the money for it. I think the "movie factory" should be more picky about what they say yes for.
