The series builds to the point that, once you learn there is a mole within the unit, you have reason to suspect it could be any of the principal characters. You're not sure who you can trust, even among the protagonists, so the writing was very careful not to give anything away. For example, in the scene when they finally trap the mole, it was cleverly scripted with a whirlwind of confusion until you finally see who it is. I can usually predict where things are going but there were a couple of times I was truly surprised by a character's actions, so I'm always happy when I can be fooled by good writing.
Tom Hughes plays the lead with calculated reticence , leading you to wonder if he's screwed-up because of all the things he's seen at work or because of a screwed-up childhood, and this is hinted at in Episode 6. All of the MI5 characters have some serious dysfunction going on in their personal lives; it's rather poignant that the people who turn out to be the standout heroes are the "outsider" cop, DC Fenchurch, and the not-yet-jaded rookie Wendy. Fresh blood is sometimes the cure to the toxicity of the status quo.
It's a shame it was only one season; it would have been nice to see how the characters progressed. Definitely worth a watch.
