Jaw dropping and unbeatable!
Having being bought the first 2 seasons for my birthday in august i have now just finished season 4 and i couldn't explain how good this show is. Certainly the best show i've ever seen on tv! In the whole of the 4 series i think that only 1 episode has been boring,but that was the point...it was relevant to the context. Anyway if you have not watche this show...you need to...now!
