I generally don't like spanish dramas. Just because they are often about the same themes and actors are not that convincing (in native language).
But this time, I loved these actors. I watched it dubbed into spanish, though. But the cinematography is AWESOME. The theme is really interesting, different.
The problem with the movie is not that it is slow paced or it has no feelings. It has a lot of feelings, the vfx / proesthetics works is amazing also, but it is that not much happens along the story... I wish there was more than just the "person who is treated like an object to get money and that ends up being a sad and terrible for everyone". It's ok for a premise but I wish more stuff happened than just gazes and people with sad faces.
Anyhow, GREAT movie. I'd love to see more of these kind of movies that are more local and more culturally similar to the real spain than others that only want to imitate what Hollywood does.
