Its the same problem with every movie made like this

Rating: 5/10 (7 December 2017)

The issue with this movie whether you love it or hate it is not the movie itself its what the movie represents and who it appeals to.
The issue being that anyone who would enjoy and understand this movie would most likely rather read a book or go to the theatre.
As a commercial vehicle this movie has next to no appeal to the masses but as an artistic piece for critics and thespians alike to enjoy it certainly will be to a point; for me personally it stepped over the line between production movie piece and expressive amateur theatre somewhere near hour and half mark.
Everyone involved within the project is clearly talented and the performances shine but as a piece for the general movie going public its a non starter. It is something more akin to what I would expect to see when attending the theatre.
If its cold outside and you are snowed in and you have read all your favourite books and can't make it out to some other form of entertainment then yes you could watch this.
If you are a fan of popcorn movies i.e 99% of other movies made for cinema then you really shouldn't waste your time watching this as it simply will not appeal to you.
I wouldn't say that it has been wrongly advertised but whoever is in charge of the press releases for the picture has done a very good job with the material they have been given. Sadly that will probably lead to backlash from the people who go to the cinema expecting to see a horror movie starring Jenny and Javier.
