I'm sad the show won't be returning (mainly because it's one of the few BBC dramas I wholeheartedly enjoy), but in some ways it's hard to see where the show could have gone. There are only so many freakish villains you can dream up before it gets a little deadening, and the personal stories for John Luther always involved tragic romances and the possibility of being exposed as a dangerous maverick by suspicious bosses. That was already getting tired after three series, so maybe it's wise to end the show and give fans a cool feature film to look forward to instead?
