There is so much wrong with this show. The plots are zero percent believable and filled with the worst sort of human evil. The flawed hero has a Sherlock Holmes-like knack of walking into a crime scene or suspect's home and immediately arriving at the needed clue (or book being used for a code in one case). In one episode, the London police engage helicopters and all available resources, but when the killer goes to an industrial estate it is left to the detectives to get there in a car, even though they have already radioed in where he is going. Like London Kills, which is a pale imitation of this show and which I have also reviewed, this series gets by on its cast, but the cast of Luther is far superior. And the writing, while still ridiculously unbelievable and reveling in evil, is bad in a much better way than London Kills. It makes it hard to stop watching, even if it means seeing people get their heads bashed in by hammers at Liverpool Street Station or while sitting in their car during a traffic jam. My goodness, things aren't that bad in Britain, and the worst crimes have been committed by terrorists, not by evil twins, fake taxi drivers, or failed art students. Surely Britain can come up with a more intelligent crime show for this stellar cast to appear in. ( )
