This is the only movie I wish I had never watched. It left me with this disgusting/angry feeling afterward. It suppose to be a good story line, but the psycho is really awkward, he is too stupid and clumsy to do whatever he suppose to be capable of in the movie, and amazingly, the only-dumber victims are even more stupid just to match him...
Isn't a good movie suppose to present a smart victim with even smarter bad guy, instead of dumb psycho with even dumber naive-little-angel-mid-age adults...???!!!
Does the movie editor think the audience are retard or something with zero common sense? We are full-time survivors of life, we have some super basic common sense... this movie is such an insult to the audience...

Cesar is the superintendent, and is one cruel, deceitful and demented character, played with a determination of a person who states he can never be happy. In the building is Clara, a perky and joyful person, who he is determined to ruin, an older woman, Veronica, who he simply is cruel to, and a young girl who knows too much for her own good, and blackmails Cesar.
Veronica is older, lives alone and has two dogs. She asks Cesar to mind them for one night, and that Rocio has a sensitive stomach, so only feed him a special food. Cesar gives the dog a pie that makes him very sick, and Cesar tells Veronica perhaps she needs to prepare for Rocio’s death. That really sets up the type of person he is. Near the end of the movie, he lies and shows a deliberate cruelty to her. It devastates her.
Cesar sneaks into Clara’s apartment, drugs her and also adds chemicals to her soap and creams, which gives her a rash. Critics will pounce upon the fact that what he uses cannot do what is shown in the movie. Yes, correct, but this is a movie, and it needs a plot line to put her unconscious. This is a pattern he continues with for weeks and weeks.
The movie slowly ramps things up, and the police start getting closer. He has sent letters, phone calls and messages to Clara, and is almost caught, as the police get closer and closer to where they are coming from. And he starts to get a little reckless.
I don’t consider this a horror movie, just an intense movie about a psychopath who shows no remorse over anything, and ruins other people. Will he get tripped up?

As a true horror/thriller fan, I was initially drawn into this film within the first 15 minutes. However, as I continued to watch (all the way till the end), I became less enchanted. The actors are great. The story, not so much. The concept is horrifying, yet somehow I was left with a nasty feeling about it -- as though I were the one being toyed with. I really wanted to like it more. Maybe it was successful in that I was left with this distaste, so I gave it 3 instead of 2 stars. It's worth a watch if you like this genre. (note: the subtitles lag quite badly, so if your Spanish isn't too good, they are a bit frustrating)

Luckily you can now buy all the security items on Amazon after you experience this movie. But they probably won't help keep you safe from this monster.

It's difficult to rank the acting roles of Luis Tosar. Just when you think you've seen him at his most demented, another starring role appears. Exactly like the twists and turns of this movie.

Really creative film-making set in one location. The screenwriting, actors, scenarios-- absolutely chilling. The music is perfect; think Quentin Tarantino's ear mutilation scene set to "Stuck in the Middle"...

Other Luis Tosar masterpieces: Retribution, Eye For An Eye, The Occupant, 1898: Our Last Men in the Philippines, Even the Rain, Adu... and more.

First, the criticism is that there were no sub-titles so we had to use close captioning and that lagged the dialog by a large margin. However, the synopsis sums it up nicely and the concierge really doesn’t like happy people and how he attacks some in his building are rather unique and makes this a pretty worthwhile thriller. It is a creepy flick and a subject matter that some may find distasteful but if get past that then it’s a pretty enjoyable movie with the usual plot flaws that are easily overlooked. It’s not a long movies and I doubt shortening it would have made a difference so stay with it for a nice little ending. This movie is getting dings and the delayed sub-titles and not to split hairs there weren’t any in what we just watched and closed captioning is not the same thing.

This movie reminded me of some personalities I know and/ or have met in my life. It inspired me to continue being happy no matter what. The actor who played the villian gave a riveting performance. Man is he good! And the actress who played the role of the victim did a great job of making you feel for her character completely! Kudos to the director and writer of this film. It was better than a lot current that have come out in the US theaters over the past several months. Watch this! you won't be sorry.

i like thrillers and horror but this was just pure torture porn. no artistry or point, i felt as if the director is enjoying the sick actions of the perp just as much as the perp is. very stupid and vile movie.

Captioning (no English subtitles) lagging behind really didn't bother me at all. It gave me the chance to watch the actors, and then look down to read what was said. Which is my wife's main complain about subtitled movies, is that you have to read and miss what is going on.

I thought this started slow, but kept getting more twisted as it went. With plenty of skin crawling, creep you out, I don't ever want this to happen to me, moments.

Good acting through out by lead characters.
