Familiarity breeds contempt, we are led to believe, but for me it gives my already crowded and complicated mind something else to contend with while grappling with complicated plots.
There is no question that Martin Freeman and Vicky McClure are both damned good actors, but it also creates a problem of their own making — forgetting their past.
The latter will always be Kate Fleming in Line of Duty — and we will come to her later — while Freeman has an impressive pedigree on the small and big screens, so you have to battle to lock out Tim from The Office, Dr Watson and Bilbo Baggins to name but a few.
I doubt though that we are going to forget PC Chris Carson, his latest incarnation, in a hurry.
The Responder is the BBC’s new gritty drama, one of many, but Z Cars or Juliet Bravo this is not.
Kate’s old mate, Ted Hastings, would not be a fan of PC Carson, who may not be a completely bent copper but is more malleable than Morph after 10 minutes in a microwave.
The huge surprise right from the off is that this small, hugely angry Scouse bizzie (Liverpool law enforcement officer) is not being played by Stephen Graham.
This may be for a number of reasons. He is likely busy, or he has played the role in x number of previous shows, but, more likely that the executive producer is a Mr M Freeman — and I’m guessing it is not Morgan.
Carson’s personal Shawshank is the breakdown he is racing towards quicker than a squad car with the blues and two on (see, I told you I watched a lot of telly).
This is multi-layered. The nightly grind of being a first responder to crimes in a Liverpool that is more like downtown Kabul doesn’t help, plus he clearly has a big family back story brewing, a dying mum and his wife is having it away with a former colleague who got him demoted.
Oh, and his bezzie mate is a drug dealer played by two entities — very scary actor Ian Hill who is overshadowed, literally, by something even more terrifying — his hair.
But our bendy anti-hero has a heart (bound to be broken) and is very happy to give baddies a clip round the ear or trail you around by the wobbly bits inside your trackies if needs be.
The realism of the show comes from writer Tony Schumacher, a former Liverpool policeman, not the West German goalkeeper who carried out an assault on Patrick Battiston in the 1982 World Cup that Carson would have grimaced at.
There are still three more parts to come. I particularly hope we see more of Kevin, or Sinbad from Brookside to me, who deals with pesky kids by use of a sword, or Davy the tramp, played by David Bradley, who looks like Worzel Gummidge after a weekend in Liverpool.
It isn’t an easy watch, but at least he has a new partner in Adelayo Adedayo to bounce ideas off. No such luck for Kate, sorry, Lana Washington, the star of Trigger Point on ITV.
She is an EXPO. This does not mean that she used to play the red one on Teletubbies. No, she is an Explosives Officer, although compared to how often PC Carson goes off, she’s like a damp Bengal Match.
Anyhow her new role that isn’t Kate in Line of Duty creator Jed Mercurio’s new show has a buddy who she calls ‘mate’ all the time and is called Joel Nutkins — no relation to Terry.
We join them at a block of flats where there is a bomb in the toilet. Is now a suitable time to make a joke about the ‘bum squad’ being called? Thought not, carry on.
This is no Lethal Weapon though, as there’s not just the one bomb in the bog, there is another on a light switch and one tied to a hijacked man who stumbles out from the boot of his car.
Lana and her lucky pliers manage to disconnect all three of these, no mean feat as she and Joel seem to spend their time quaffing huge amounts of energy drinks and listening to gangsta music.
Maybe it was just me, but you could have set your clock for another bomb turning up every 12 minutes or so as it being ITV, we had to leave you hanging over all the ad breaks.
There was no ad break for the fourth and final bomb — just the end credits for Joel who went to check that one last vehicle and Lana’s earlier joke that she loved her mate to bits came all too true.
It’s not Line of Duty or The Responder but it’s like a box of Pringles, once you pop, you can’t stop watching.
