I may firstly say that I love some of the people who appear in this film, and one of the actors is someone I love dearly since childhood. They've had pretty heavy roles in some of the most controversial Mexican series of recent times. Their acting is usually very good, but it's a very different thing to make a long-haul telenovela to a proper feature.
Said that, this film revolves around a house, a cat and a bunch of girls and a weird lady that try to make us feel uncomfortable. The problem is that they don't succeed on the task. And that's supposed to be the very raison d'etre for a horror movie. If you can recall acting as contrived and stiff as the old lady's, well... I have to pry my brain open to remember one, apart from some very bad comedies.
Kudos for the location, cinematography and 3D. The post is superb. Lighting, audio and props, top notch... what you'd expect from a much more expensive film.
Thumbs down to the story-telling and the over-the-top acting. These girls could be very nuanced and subtle in some other films, but here... well, yeah, OK. Eréndira Ibarra may be one of those rare gold nuggets that needs a film just for her -this wasn't the one. And I KNOW for sure, she needs a film of her own, because she's a fantastic actress. Here, she's just the cussing tough one.
I guess the main problem is all the characters are fleshed out of their own stories and little is revealed to have the time to connect, empathize or feel for them even a slight connection. That puts them out of the way as you can concentrate more on the house, the furniture, the props... which... well, all of them are beautifully captured in glorious 3D.
So, in the end, they've got a very polished result, visually, but without bones to lay your teeth on.
