This won't be everyone's cup of tea. But it definitely is mine. Never before has there been a more convincing TV show, in terms of its plots, dialogue and characters, and this is largely down to its unscripted format and documentary-style filming. Naturally, there's never going to be award-winning artistic cinematography or Hollywood-esque dramatic lines, but that's what makes this show different. You get utterly transported into the working lives of the three detectives, as if you're a fourth party watching over their shoulder.

With the exception of the first and second episodes of the second series, each episode has its own crime to be solved, meaning that there's no grand story arc to follow, and you can dip in and out of the series; missing an episode is no problem.

It's also a breath of fresh air that there's no personal rubbish with the main characters. Sure, sometimes a case gets a little close to home on the occasion, and DI Martha Bellamy noticeably has pictures of her kids on her desk - little touches of believability like that - but other than that, the focus is on the plot and catching the criminal. As it should be.

As someone who has grown up watching Poirot, Sherlock, and countless other crime-solving dramas, you'd think they'd have had enough making these things, but nevertheless the plots keep coming, and the plot twists in this show are actually unpredictable. You yourself are a detective, trying to thread the clues together alongside Jack, Martha and Charlie, and it's certainly a tense ride.

I feel this show will 'revolutionise crime drama', as The Guardian has said. Although the format is foreign and takes a moment to get used to, it's something I don't regret watching. Well done, Channel 5.
