Charlie Brooker basically doing for dour British police procedural what Airplane did for hysterical disaster movies. In fact this is so closely modeled on the Zucker spoof principals means that in some ways this is more of a tribute to them than it is to the UK crime shows. It's so niche a tonal combination that it alienated many at the time and it has been consigned to the cult bin. Good. I live in there.
This takes the form of three "series" composed of a single plot each - much like the ITV Britcop dramas it lampoons - John Hannah and the great Suranne Jones are magnificent as the "straight-faced" leads although Rhind-Tutt's camply pompous Tom Boss never quite works. The wider cast is a minor who's who of British character actors like Brian Cox, Stephen Dillane and Adrian Dunbar and in the last series you even get a pre-Hollywood Karen Gillan which feels genuinely insane. The first and second are notably stronger than the third but I'm secretly quite glad it didn't get the twelve episodes it was initially mooted to have (!)
The style is a heady cocktail of overwhelmingly relentless sight-gags, puns, format parodies, background jokes, wrong-footers, double entendres - you name it. It's a breathless whirligig of humour - not all of it lands, some of it is dated already, or childishly scatological, or incredibly clever, or baldly hilarious, or absolutely brilliant. It rewards repeated viewings, it's tremendously fun and it's almost exactly my sort of thing so fair play to it for that and it's the sort of thing I'm nearly daily reminded how glad I am that it even got made in the first place.
