There's no denying that it's a smart move to take the show off the air on a high - it's a huge achievement that it has run for coming up to ten series and has kept viewers captivated. Yes, Spooks has had its low points, but there has been true quality from start to finish.
Right from the very beginning of Spooks, we knew this was a different kind of show. It's hard to remember now, because we've all become so used to it, but even the style of the show was exciting - split screens! And, of course, the second episode brought us that shocking death. Lisa Faulkner was used a lot in the promo material for Spooks, so seeing her character getting dunked in a deep fat fryer was a bit of a surprise, to say the least.
But that's the moment when viewers realised that Spooks wouldn't always play by the rules. The writers weren't afraid to kill people off for the sake of the story, and no-one was safe, no matter how famous they were. For once, this was a show with real tension - you could never be certain that the good guys would survive. Everyone from Hermione Norris to Rupert Penry-Jones has been bumped off. Personally, I'm still grieving for lovely tech geek Colin, who met his maker in 2006 when he was hanged by corrupt MI6 spies. Poor, poor Colin.

As well as the deaths, though, you always had to congratulate the writers for some incredible foresight. It's strange watching the show, knowing that it had been written and filmed a long time ago and yet somehow reflected what was going on in the news that night. It often felt like the people behind Spooks should genuinely be working in the intelligence services, considering that they always seemed to have an uncanny ability to know what was about to happen in the world.
It's not surprising to look back and see that Spooks premiered in May 2002, less than a year after 9/11. The show reflected the public's mood and tackled some pretty difficult questions - is torture ever acceptable? What should you do when letting some people die will save others? Is terrorism justified if it's to raise awareness of, say, environmental issues? Spooks was dealing with tough philosophical ideas at its core - and all during primetime.
Of course, that's not to say that there weren't some stunning action sequences too. Spooks has had more shoot-outs, bomb explosions and car chases than you could shake a stick at, but it's also had more innovative terrors as well. How about biological weapons or the destruction of the Thames flood barriers? And one of the sequences that will always stick in my mind is the dread-filled, terrifying chase through the London Underground. Spooks could really have some heart-pumping, dry-mouth moments.

We also have to pay tribute to the show's astounding cast. As well as Faulkner, Norris and Penry-Jones, we've seen stars like Richard Armitage, Miranda Raison, Matthew Macfadyen, Keeley Hawes, Nicola Walker and Anna Chancellor grace the Grid. And that's without even mentioning Robert Glenister as the Home Secretary (who gets bonus points for his chilling death scene, when he was poisoned by Harry), Gugu Mbatha-Raw, Jenny Agutter, Max Brown, Simon Russell Beale and Laila Rouass among many, many others. But no love letter to Spooks would be complete without mentioning a certain Peter Firth.
Harry has been the one constant in Spooks. In a show where you could never be certain who was safe, Harry has been the thing that keeps it all together. You never knew whether Harry would survive, of course, and he's not always "done the right thing". But his presence was reassuring to viewers and Spooks wouldn't be the same without him.
So, while it's a good decision to end Spooks when fans still love it, that doesn't mean we're not going to miss Section D. But Tube Talk can tease that series ten will be all about Harry, and we can say with some confidence that it's going to be a belter.
