One quibble I had with the film (slight spoilers)
Is the opening scene has marta discovering the body and showing genuine shock, when she already knew exactly what she would find as she saw him with the slit throat the night before. This was a cheap attempt to throw us off Marta as a central figure in the crime for the first third of the movie and should have been done better IMO. Other than that, it had the typical overly convoluted plot of the whodunnit genre. While not a bad film, I think the praise for the film is due more to casting a latina as the lead (the beuatiful Ana de Armas) than the film being great in its own right. However, to treat this casting choice as trailblazing, we would have to ignore the fact that actresses like Selma Hayek, Eva Mendes, Rosario Dawson, and Penelope Cruz have been around for decades.
