These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Moment of Awesome: Miles's "acceptance" speech for his award for bravery, in which he calls out the assembled higher-ups for punishing and shunning Chandler for saving his life instead of chasing the Ripper suspect in the same incident for which he got his award. It's also heartwarming and hilarious.
Miles: "So thanks for this, but no thanks. And I just need to catch a bus back to my table."
Big Lipped Alligator Moment: In the third episode of series three, Mansell is searching a house when he notices a photograph of a girl on the wall. Without touching it, it falls off the wall, and after he makes a run for it, there's another shot of the photograph, the girl's expression having changed from happiness to fear. It's never explained, and apart from Mansell being spooked for rest of the episode, never brought up again. Though in hindsight it could be seen as foreshadowing to how series four starts introducing supernatural elements, it is still never adressed.
Magnificent Bastard: Anderson in series 2, having manipulated everyone, including the heroes and even the Krays to gain a position of power.
Paranoia Fuel: The odd behaviour of several cops throughout series 2, who may or may not be working for the Krays.
The flickering lights and dodgy pumbling in series 4 that may or may not have a supernatural cause
The Woobie: DC Kent, the youngest member of the team and the only one to be nice to Chandler from the get-go. In the first series it's revealed that he deals with the stress of his job by hiding in a car park and crying. In the second series, he's striped (an extremely painful knife assault involving long, deep slashes to the buttocks and upper legs), and suspected of being the mole, leading to a breakdown in the parking lot.
What an Idiot: Chandler yells at a PC for letting out a suspect accused of murder from his cell. The constable says that he thinks he was confronting the devil. He was subsequently suspended from duty.
