Luther is show that only works because of Luther and Alice. The criminals in the second and third episode have been boring and surprisingly average considering how great Alice was in the first episode. They lack the shock factor of most Criminal Minds psychos and aren't nearly as cunning as Alice. "Episode Three" features a deranged killer who previously evaded the police until Luther, predictably, mindgames and arrests him.
Alice is still scary in the third episode, doing whatever she wants to antagonize Luther. This time around she decides to beatup Mark and blame it on Luther, although by Luther's request, she gets Mark to recant his story. One thing I don't understand is that if Alice has been doing all these things, clearly in public view, why has Luther not taken it to Rose so he can be more aggressive in his investigation? After all, shouldn't Alice be a person of interest in her parents' murders?
Score: 8.5/10
