Superb TV show. Sometimes a first series can be a little disappointing, making it harder for a show to keep running, but this is just great. It's very dark, but the story is so wonderfully told. Also, I'm not usually one for style over substance, but the cinematography of this is just beautiful - it will definitely pay to get the bluray! On that point though, the substance is there, along with the style, to make a great show with some excellent acting performances (Mads should definitely pick up some awards for his Hannibal).
This show needs to be seen by more people; buy it, tell your friends about it, you'll be thankful you did.
