Javi Puyat’s review published on Letterboxd:
Perhaps one of the most gripping, mesmerizing films of 2014. This film is all about character evolution, and as one of the most unique things of the movie, the evolution of a eccentric semi-likable hero into a ruthless, unsympathetic sociopath. The acting of Jake Gyllenhaal iis amazing, and as a character he is impossible to keep your eyes off of. He literally steals every scene he's in.
