If you look at the British series, it's much shorter, and for good reason.
The opening scene for the season 1 had me hooked. They defined that character so well with that opening scene and I was immediately interested to see what this character was willing to do.
Then season 3 happened and I find he's turned into every other character in every other modern show.
I wish they had taken the approach of just making him ruthless towards the other nations in achieving the US's goals instead of the direction they went in.
Maybe they are too focused on their new exclusive shows to stay on top and make sure the new old ones are also good?
It's not quite "Breaking Bad" levels of tension and machination but it's a good, slow burn that really picks up as it moves along. Doesn't hurt that I just got back from my first visit to the Keys right as this came out.
(Although his blind act was much weaker in the first season...)
