Possibly the best Series?

Season 5 and 6 are my favorites.Season 7 was also pretty great, I just miss Adam in it (I'll never get over him, sorry!) I loved that they start using split screen, I feel it gives more dynamism. I loved the story lines and the arrival of Ros.
I just watched the last season of 24 and I feel like Spooks couldn't be as far as 24 as it is now. They might have had more spectacular fights and all but there's still this complexity of the role of secret services and this reality touch that makes Spooks so amazing. They always avoid the black and white clichés and deal with the thin line of morality with a lot of subtlety.
