I have seen the first two episodes, and was disappointed only by the fact there will be only six, and then another six. Cast is fantastic, and though the dialog requires higher volume for these American ears, it is well written. I usually wouldn't watch the screen version of a book I might like to read, but I wanted to see this as soon as it came out, and didn't know if the books. I'll definitely read them later though. The theme song. As soon as I heard it, I thought, "Surely they didn't get Mick Jagger"?! But it is, and the song is cool, with relevant lyrics and thematic elements of the score too. I see several reviews complaining about a 'leftist' bent to this one, but all I see is art imitating life with some of the plot lines. I recommend this one, unless you don't like elevated espionage fare. It's good, real good based on the first two hours.
