This is Jinsy, Sky Atlantic

Excepting the cows, Guernsey’s most famous resident was probably Oliver Reed, who lived there as a tax exile. The barmy This is Jinsy, the creation of Guernsey natives Chris Bran and Justin Chubb, probably isn’t a faithful depiction of the island’s life, but it’s got to be its most notable cultural export. If not that, then its most curious.

Jinsy is an island. Its population is 791. Dotted about the place – in homes, too – are 1067 tessalators, surveillance devices that look like old-fashioned parking meters. The tessalators issue edicts and show TV. Living in numbered chalets, the lives of Jinsy’s residents are overseen by the vain arbiter Maven (Chubb) and his straightman assistant Sporall (Bran). Operating from the Great Tower, Maven and Sporall are instructed by the unseen Great He. Local laws are interpreted by the always dripping wet Trince.

This second episode in the new series was a typically bonkers peek into the world of Jinsy. Eric Dunt, a cupboard salesman, convinces Jinsy he’s the Great He, so the islanders start wearing his cupboards (Peter Serafinowicz as Dunt with Justin Chubb, pictured right). But Sporrall is sceptical and, pissed off that his love Soosan Noop has fallen for Dunt's charms, decides to expose the seedy salesman. Along the way, show regulars appear: a couple of seagulls chat gnomically, Joon Boolay administers punishments, Tracee Henge does the weather report and Mrs Goadion gossips while guarding the tower.

In the tradition of every crazy, surreal British comedy of the last 20 years, This is Jinsy out-weirds them all. It’s hellishly funny too. The island’s take on animal testing is not what you’d expect. Early Reeves and Mortimer, Teletubbies, Father Ted, Psychoville, Look Around You, the first zoo-set series of The Mighty Boosh – all are in there. Along with Monty Python and Rutland Weekend Television. And The Prisoner.

This is Jinsy was first seen in March last year as a pilot on BBC Three. A series didn’t follow, even though it was nominated for a comedy Rose d'Or at the Swiss annual international TV festival. Luckily for Bran and Chubb, producer Lucy Lumsden moved from the BBC to Sky and picked it up.

Although writers and stars Bran and Chubb are new to TV, This is Jinsy's director is Matt Lipsey, who helmed Psychoville. The safe pair of hands suggests caution from Sky Atlantic for its first comedy commission. Recognised names are presumably cast to hook viewers in a similarly bet-hedging way. Harry Hill appears each week as Joon Boolay, looking startlingly like a dragged-up Stanley Baxter. A wildly over-the-top David Tennant was in the first episode. Jennifer Saunders is the voice of the tessalators. Simon Callow, Jane Horrocks, Brian Murphy (George of George and Mildred), Nigel Planer, Catherine Tate (seen with Justin Chubb, pictured left) and KT Tunstall crop up later in the series. Look Around You’s Peter Serafinowicz was this week's rogue cupboard salesman.

The caution is understandable as This is Jinsy is, well, weird. Next week, the goings-on at the island’s annual beard competition are revealed. Maven is more concerned with being the cover star of Glove Hygiene Monthly, whose editor, Roopina Crale, is played by a wonderfully off-beam Tate. When they first meet, Maven can't get his glove rituals right, implying he's not as clean as he should be. He ought to be paying attention to the mysterious beard thefts plaguing the island.

Cult is daubed all over This is Jinsy. This is not a criticism. Chubb and Bran’s vision is right now’s furthest-out, making it more than a TV spotters delight. It’s addictive. After each episode, you want to see another. Then you want to see it again to find the bits you’ve missed and work out what that “eh?” moment was really about. But you wouldn’t want to move to Jinsy.
