You have to admire the Brits.  If they have a successful crime 
series, they don't automatically grow it
beyond one season (Midsomer, 
excepted.)  But the trouble with most crime series filmed, and also 
successful crime series in print, is they go beyond their best before 
date.  And by this I mean, they start to run out of plots - healthy 
original plots - and search madly for something, anything they haven't 
done before, including things that have been done to death <sic>. 
 The following tropes drive me crazy.
1.  The protagonist sleuth is the murder suspect.
By
 far, this one has me fired up to throw things.  Inevitably, every 
long-running series has one episode where the Detective Inspector, the 
PI or the well-respected amateur sleuth, becomes the prime suspect for a
 murder well into the series.  Into jail they go.  They've done it with 
Father Brown.  They've done it with Don Matteo.  Hinterland.  You name 
it.  Whenever I see this happening, I grit my teeth.  Why?
That
 plot is boring, man.  Obviously, they didn't do it.  If they did, then 
it is 'series over'.  And it can't be series over, because there are 
several episodes left, or a new season to download, and I can see that 
right on the screen.  So all we're doing is tediously waiting for the 
sidekicks to get proof that our beloved protagonist didn't do it.
2.  The protagonist and/or sidekick is held hostage.
This
 is the second plot trope that has me screaming Italian curse words at 
the screen.  This month, it was Don Matteo and Rosewood.  You can name 
others.  And again, this is boring. If they are all killed and don't get
 out, end of show.  But there are more episodes, so they obviously get 
away.  If we know the ending at the beginning, what's the pleasure in 
watching?
3.  The police officer protagonist is hated by his immediate superior.
One
 of the reasons I like Endeavor is because Morse's boss Thursday is such
 a good guy to young Morse.  In so many shows, including the original 
Morse, the detective superintendent or chief constable behaves like an 
out-of-control teen, lambasting our hero with manic fury.  He hates the 
protagonist, for no good reason we can see.  Or is it that he is so 
insecure, he can't stand someone who makes him and his department look 
good?  How demeaning.  By all that's holy, make this stop.  
4.  Young female sargeant has affair with older boss.
Okay,
 we all learned in the 80s and 90s: you don't have an affair with your 
boss.  It's stupid. It's career-killing.  It's also unethical, if he's 
married or you're married.  And yet, time after time we see this on the 
screen.  STILL.  IN 2018.
I cringe, because it 
perpetuates the ancient stereotype that young female police officers are
 not serious about their jobs.  They are slaves to their emotions.  They
 are willing to risk all for romance.  Writers, DON'T take me back to 
the seventies.  Just don't.
5.  The male Detective Inspector invites prime female suspect/witness to a romantic dinner.
Similar
 to the 'affair with the boss' above, this scenario gives high-ranking 
police officers I've talked to apoplexy.  No police officer is that 
idiotic.
Look, we all understand that tension is 
ramped up if there is personal involvement.  But come on, writers!  
Don't make our extremely professional boys (and girls) in blue look 
adolescent.  It's insulting.
Just do the right thing.  Tell us a damn good story. And wrap things up before you sink to these tropes.
