I'm up to season 7 now of the 10 seasons. I read recently that 10 seasons is all they will do. I have thoroughly enjoyed the series, the character development and particularly the plot and character twists, turns, about faces and secrets. Keeps you coming back for more. Add to this the brilliant acting pathos of Spader and you have a great series. Added bonus: seeing Spader recreate (sort of) his character Alan Shore from Boston Legal on episodes involving trial in the Federal Courts. Sweet! I recommend this series to anyone with a fancy for spies, crime, secrets, espionage and deep character interaction. Fun!
