I was a fan of the telly series, but i was badly let down by this film. Luther’s psychological struggles such as why he has a „death wish“ go unexplored, whilst the serial killer is given way too much prominence. The film becomes unwatchable once the characters reach the snowbound lair of the killer. I fast forwarded through the torture scenes in the lair. The film was already too graphic with its delight in sadomasochistic „red room“ porn and it went over the top at the end. I regret watching this. A disservice to the Luther character.
