I watched this last week and despite having not seen Spooks for years, I thought this was a satisfyingly taut, tense international spy thriller which could have made for a decent Professionals story with some tweaking here and there. Kit Harington (Jon Snow in Game Of Thrones) was a suitably troubled, feisty young hero whose job was to bring in disgraced secret service boss Harry Pearce who was under suspicion for letting a terrorist escape custody. He goes AWOL and the mind games slowly unravel as Harington gets closer to him. Pearce claims he is after a security leak but you don't exactly know if he's a good guy or a traitor until the final reel. His machinations reminded me of the sort of games George Cowley would instigate in the more cerebral Pros eps.
This movie has the same hard edge as the recent Bond movies but the action is more realistic in an SAS-style kind of way and young Tuppence Middleton provides some posh eye candy as another agent you're not quite sure of in terms of trustworthiness.
"What was I thinking of, hitting him? Nothing. No, I know. I hate him! I hate his guts, I hate everything he stands for with his PACE and his plus and his statements of purpose and his smiling at the punters and his have a nice day! I mean when was the last time he ever nicked anybody, eh? A real villain! When was the last time he ever put himself on the line?"
