I don't know about you but I've watched a whole shedload of UK based police dramas and once you learn pretty much anything about how the police have to obey rules, and that there's a methodology to police work, then you get a sense of when something is well written, even though it may be unrealistic.
But this...this.. is just unbelievable in almost every respect.
Countless times it sacrifices any sort of realism for cheap thrills and although I watched it until the end, then that was more because I was laughing at it rather than admiring it.
If you're looking for a reasonably well acted drama but with a mediocre script and an absurd sense of "turn it up to 11" plot where you need constant stimulation then this is for you.
4/10 is about right since it held my attention enough to watch until the end, but it's below average for this sort of production.
