So I been watching Luther, and it isn't a bad show. I couldn't help but notice that it was a new twist on the Sherlock Holmes template. Knowing that you probably finished the series, I'd like to return the favor and recommend one to you. Have you ever seen the new British version of Sherlock Holmes? It is a modern adaption on the old series, with a very interesting story line, a young Sherlock Holmes, and great actors (I particularly love Moriarty whom I had hated at first, but now I think is absolutely Brilliant!!!). I know you will like the fact that the star of the Hobbit, Bilbo Baggins plays Sherlocks sidekick Mr. Watson. It is a short series of only about three 90-minute episodes of 2 series with the third one coming out in 2014. I don't know how they can top off the second series, but hats off to them, and the better for me if they do.
Best part is that it is on Netflix! If you have it.
