Hannibal is my favourite new TV show this year, it is fantastic. It has a great cast, most notably the two leads, Hugh Dancy as Will Graham and Mads Mikkelsen as Hannibal. Will Graham in this version is far more unstable, which leads to some great sequences where he has to question his sanity. Mikkelsen plays Hannibal in a very different way than Anthony Hopkins did in the movies, this Hannibal is a lot more subtle and restrained, yet he is still incredibly charming.
I cannot recommend this show enough.
One warning though, it might be the goriest thing that I have seen on television
