If you get a chance to read the novel written by Ken Bruen upon which this movie " Blitz " is based on, you will miss quite a lot in the transition. Even though the movie is graphic, the book is more so. In addition, the main character Detective Sergeant Tom Brant (Jason Statham) is definitely more violate and his partner DI Craig Stokes (Luke Evans) is revealed to be more incisive and meticulous. Indeed, the suspect called 'The Blitz' (Aidan Gillen) reads more intelligent, clever and evasive. Having read the book and seen the movie, I will say that both are dark and similar to the point of eeriness and memorable. The movie is a black insightful look into the mind of a serial killer and with Statham chasing him through the streets of London, far more exciting. The story is fraught with loose ends and indeed some are not resolved. Still, it is a good attempt of keeping the audience interested. Since Jason Statham is the leading man the finished product can be said to be dramatic enough to be recommended. ****
