Back in the real world it's nothing like that (I know, my long-deceased father 'helped out' with Britain's SIS and told me a thing or two when he reached his dotage and he wasn't a show-off. Like 99.9 per cent of all like him who 'helped out' he was very discreet).
That makes many claims here in other user reviews complete nonsense: for example: 'You've got to peek (I think what the writer means is 'you get a peek') at the ugly workings in the intelligence and private military world'. Oh really? So how would the writer know? Did a bit of spying between leaving uni and getting a job running the Waitrose in Alderly Edge?
Intelligence gathering is necessary in even the dullest and most mundane of international dealings - knowing what the 'other side' knows or think they know can be very useful indeed and they are all at it. But 'spying' is not glamorous and can often be exceedingly dull, involving days and weeks laborious and monotonous trawling through list, files and I don't know what else before any analysis of what is known can be made and plans shaped. As for a department being run by just one man with apparently no need to clear matters with any superior of any kind and who can order assassination as easily as a skinny latte, well tell that to the marines.
OK, you say, but this is TV entertainment so don't get so anal and picky. Fair enough, but even as a piece of TV entertainment Deep State gets only two cheers, if that.
The story is both obscure and vague enough to carry you along but is distressingly two-dimensional. The various characters have no problem at all travelling between countries at the drop of a hat (one chap, dropped off in the back of beyond on the Turkmenistan managed to get back to Teharn - more than 500 miles away - with apparently no hassles at all and got straight back to work. Give that man a medal! The men never seem to need a shave, have access to unlimited funds, despited looking like tramps on their uppers never attract the attention of the police and never, ever, ever seem to charge their mobile.
I have gone to town a little because inexplicably Deep State gets an overall 7/10 from assorted fanboys but at the end of the day it is just one of several hundred such series produced annually the world over. It's not bad by any means, but it's not particularly good either. And because I have seen far better, it is irritating that the producers go for second-best because really that's all they need to do.
Whether or not this is your bag depends on your standards. If you want just the usual evening TV thrills with predictable lines and predictable plots, go for it. If you like something a little more challenging, give it a miss - you won't be any worse off by any means.
LATER: A few more episodes down the line and appalled by how bad Deep State has become, I couldn't resist an edit to say so.
Deep State really is the most one-dimensional twaddle I have chanced upon. Certainly there are contenders for silliest 'thriller', but Deep State has a head start. Since I wrote the above, the 'hero' and his son travel from Lebanon to France with ease, pick up two high-velocity rifles with ease, get involved in a gun battle which attracts no attention whatsoever, eventually cross the Channel where just as he is about to torture his former MI6 boss, the boss kills himself - and on and on and ridiculously on.
Deep State is not intended for those who have a small brain, but for those who have no brain at all. It is garbage. Don't bother unless you don't mind admitting your are less intelligent than a flea.
