A little unrealistic, but good entertainment. It never promises to show the actual reality of armed police life. But at times it does dive a little into their personal lives. Ronnie Pike's character shows he has a stable, settled and prosperous life ahead of him. Bishop's is quite volatile and unsettled.
I don't think it is trying to be a Bad Boys British rip off. Both agents Bishop and Pike are "alpha" males. Whereas with Bad Boys, that wasn't totally the case.
Not sure why it has so many thumbs down. It does look at the gritty side of London, rather than the High Life.
Acting could be better, but it is no way terrible acting. Not everyone will act like Idris Elba, John Simm or Matthew Macfayden.
Always enjoy Ashley, Noel and Christina
