That is a new wave of gothic horror mixed with social critique, its most famous representative being Mariana Enriquez. If you like this film, you should definitely read "Things we lost in the Fire" or the fantastic "Our Share of Night" which has just recently been published in English. Demian Rugna is obviously familiar with that book, there are many similarities, especially the gore. I would not be surprised if he adapted it next, hopefully with a much higher budget, which is the major drawback of this little gem. This is a fairly good possession movie but there are some major continuity problems and the climax is weak. Still, better than anything genre coming out of the US this year.
