Cinema time ! : Behind the walls (Detrás de las paredes)

Yesterday I went to the cinema with some friends, and we saw that movie.

Will eightenten, a writer, bought a new home. Soon, he and his family realised that in that house are passing weird things, like seeing black-masked men spying them through windows or teenagers doing black magic in their basement. Will discovered that in the house there were 3 murderings 5 years ago, and the murdered ones are his family, killed by him.
He was seeing ghosts... Will began a investigation, sure that he couldn't kill his children and his wife; this is dangerous, because the real murderer is free, somewhere... Wanting to "correct his mistakes".


Opinion

I was looking for a suspense film, and it was like suspense, but very, very bad... I though I was going to sleep. I don't like it at all, because it don't have much... "hook". At the end, it had the worst finish I remember; all the people in the cinema were asking "Is it finished? Really?", because it gave an empty sensation (As you're noticing, I don't know how to describe this exactly). There were some too boring scenes.
The most I liked was the images and the scenarios. Also there was few sensitive moments, but there weren't very deep at all. The soundtrack was very low for a suspense film, and I don't like the plot, which, from my view point, is like a child story (all have that "strange" finish).
I don't recommend this movie to anyone, because I think it's better to see other suspense films (like "While you're sleep", for example; a good one). I think it was the worst movie I ever seen in the cinema.
Well, it works good being an excuse for meeting my friends; that's what I liked the most.
