[spoilers] what is the best series of spooks

[Silktie]

I think season 4 is my choice. It had Adam at its best, my boy Zaf having some good moments, and some fantastic stories. Malcolm and Colin were seen quite a bit, Juliet was introduced and had some wonderful sparring with Harry, and Harry and Ruth were just beginning to realise how much they liked each other. There was a good balance between doom and gloom and some lighter moments, and wonderful friendships between the team members, and Adam/Ruth and Adam/Zaf in particular. It had a real sense of the team being a team.
