LOVE crime shows that aren't super graphic. Especially British ones.
I'm better than most, I think, which is why I LOVE when shows are clever enough to intelligently hoodwink me. I say 'intelligently' because I HAAAAAATE it when shows have this lame twist at the end like "ta da! It was this shoe salesman we never talked about!" You have to give us a chance to solve it, people. Bringing in a killer/thief/criminal out of left field isn't clever.
(Right now S5 of Downton is KILLING me with the whole "who killed Greene?" thing. No spoilers, please.)
