As NB said, love Criminal Minds, also NCIS, CSI *but not Miami, I mean what is the like of David Caruso as an actor people have - bloke can't act to save his life!*
Erm, a number of different UK dramas that are no longer airing, Bad Girls being one. Also a show that didn't get the credit it deserves (imo) and that is - Taking over the asylum - which had Ken Stott and a young David Tennant in. Was dark, funny, sad - you name it, they managed to put it all together. I believe they did repeat it, only briefly on one of the more obscure BBC channels a couple of years ago, and released a DVD. Only really because of David T and his role in Doctor Who. It won critical acclaim though, and I think some Bafta's.
Also watch The Mentalist, as well as Lie to Me - although I've found the latest season a little too staid and predictable. And a lot of sports.
