A sckanner darkly

Well, I've just finished the book from Phillip K. Dick, and I must admit the resemblance and careful adaptation of the homonym film by the director Richard Linklater. Unquestionably he had stars such as Keanu Reeves, Winona Ryder, Robert Downey Jr., Woody Harrelson and Rory Cochrane, who made possible to bring to the screen the anxiety, paranoia and addiction already in the original book characters.
Furthermore, the special effects using action photography overlaid with an advanced process animation that makes it look like a comic contributed even more to this psychedelic atmosphere.
