I watched the first 4 seasons of this series and it just gets sillier and sillier with each season. I can't say for sure but the idea that any "secret operative" of any agency would tell the young child of a lover that they are "spies but don't tell anyone ever" is just absurd! It seems like they just brag about being spies a bit too much to be believable. The plots become repetitive and nonsense the further on in the series I get. If you want intelligent television try watching "The Newsroom" or "The West Wing" which I consider two of the best TV shows ever broadcast. I would hate to think this is a realistic portrayal of MI-5. It seems to me that real life MI-5 agents must find this program laughable and probably hate the ridiculous image of their service that it portrays. Don't think I will bother with season 5 onward.
