What TV programmes would I like?

Don't know why, but I have gotten into subtitled detective dramas of late: Wallander, The Killing, Spiral, and the three Stieg Larsson films. Nothing seems to be good on the telly, so I am considering getting a DVD or something. Any ideas? I also like Dexter, CSI, and all ITV's Poirot adaptations. I do watch TV that doesn't involve people being done in, but that is not what I'm thinking about just now.
