Apparently this is a sort of a sequel, as I just read from another review here on IMDb. I didn't know that and I haven't watched the other movie. I watched this as a standalone and I think it works pretty good too.
It has great Spanish actors, it has great cinematography and it has nice twists. The movie does not differ that much between good and bad characters (you could say, that everyone has both sides more or less), but still manages to develop them neatly. I really like those twisted little movies and this one didn't disappoint (quite the contrary). Of course not everybody will love it as much as I do, but if you like thrillers that are a bit bleak and dark too, then you won't go wrong with this one.
