I love this series and I love Mum and Dad Goodman (Tamsin Greig and Paul Ritter). When the "bambinos" turn up for dinner on this particular Friday night, dad - mildly deaf and obsessed with his aged copies of New Scientist - emerges from the garage clad in a vest, shorts and cut-off wellies. "Why are you dressed like that like a sex attacker?" wonders Adam (Simon Bird). What follows is the usual collision of family in-jokes, misunderstandings and general silliness. Dad has been ordered by mum to burn his beloved magazines, but he's mapped out a ruse designed to pull the wool over her eyes. Meanwhile Aunty Val (Tracy-Ann Oberman) is on her way round to show off her mother-of-the-bride dress. I am delighted to admit that I laughed immoderately all the way through; at the gag about the mobile stuck on speakerphone; at neighbour Jim (super-twitchy Mark Heap) and his supernatural fear of his perfectly timid dog. And at dad's Join The Dots Sex Book. Don't miss.

Apart from the smatterings of mildly bad language, this Jewish take on My Family remains a surprisingly cosy sitcom for a Friday night on Channel 4.

You can't fault the cast - which includes Simon Bird and Tom Rosenthal as bickering brothers who revert to toddlerhood every time they step through the front door into the family home.

The dramas are small ones and this week a family squabble manages to break out over the colour of mum Jackie's new curtains. The bright spots in all this are Paul Ritter as the bare-chested shirt-phobic dad and Mark Heap as the oddball neighbour Jim.

Those three little words: "And Mark Heap" at the start of any sitcom are like a British Standards kitemark guaranteeing that there'll be nuggets of bizarre brilliance tucked away inside - and tonight's scene involving Jim's trip to the pub with his lager-loving dog is very odd indeed.

Another Friday night, and another borderline gruesome family dinner with the Goodmans. The hapless, girl-shy Adam (Simon Bird) faces yet another painful interrogation about "females", or girlfriends, from Dad (the magnificently weird Paul Ritter): "Don't call them females" Adam whines, "they're not corpses." Tonight batty granny visits and upsets Mum (Tamsin Greig), who's already feeling generally unappreciated, by dissing her new curtains. But the most sublimely stupid bit of the episode involves barmy neighbour Jim (Mark Heap) and his dog. This superb beast does the best drunk-acting I have ever seen on television when Jim takes him to the local pub, a ghastly hole called the Black Boy. Dogs shouldn't drink beer. Really, they shouldn't.

A family comedy like no other, Friday Night Dinner is well on its way to becoming the kind of small-scale Channel 4 hit that keeps the cognoscenti coming back year after year. The chemistry between Tamsin Greig, Simon Bird, Paul Ritter and Tom Rosenthal is terrific. Tonight's antics revolve around gin, bin bags and Mrs Goodman's efforts to improve the living room décor; it's astonishing how much comedy can be mined from a pair of pee-coloured curtains.

The boys arrive home to find Dad still naked from the belt upwards. But that's the least of their worries when they spy him behaving very oddly through the window. Paul Ritter, as dad Goodman, continues to be a comic revelation. How is this his first leading role in a sitcom? Writer Robert Popper's now-established comic rhythm is pacy and fresh in a way you wouldn't expect of a family sitcom. And this episode concludes with a last line that wraps it up so perfectly, you'll want to wind back and watch it again.

Friday Night Dinner is turning into a tiny treasure. It's not an eventful sitcom but my, it's a funny one, with streams of uncomplicated laughs. There's a scene in a car with a VERY LOUD stereo that left me helpless; I watched it three times before I had to be dragged away and sedated. Writer Robert Popper has nailed the in-jokes, the petty embarrassments and routine bits of silliness that make family life fun, and not in a broad, pantomime-hapless My Family kind of way. Friday Night Dinner is full of surprises and the cast work together seamlessly; Tamsin Greig as a good-hearted, slightly ditzy mum, Paul Ritter as a well-meaning, barmy dad and Simon Bird (yes, Will from The Inbetweeners) and Tom Rosenthal as their grown-up but daft sons. It's endearing, too; everyone loves each other, which is why they are so comfortable with embarrassments. Well, most embarrassments. Adam (Bird) isn't too keen on being quizzed in the downstairs loo by his dad about "females" (ie girlfriends). "Do you have to call them females? You're not a policeman."

Tonight's second episode of this new observational comedy hinges on Martin (Paul Ritter) peering down his underpants with a magnifying glass when he thinks no one's looking. His grown-up sons, who've witnessed the spectacle, spend the episode wondering why. This promising comedy about embarrassing parents is quite fresh and funny, and if it lacks the bite of The Inbetweeners (whose star, Simon Bird, plays son Adam here), it's more family-friendly.

Surprisingly traditional family sitcom from Look Around You's estimable Robert Popper. Green Wing's Tamsin Greig, Paul Ritter, Simon Bird from The Inbetweeners and Brass Eye's Mark Heap star as the Goodman family and their odd neighbour respectively. It will draw comparisons with Grandma's House in that it's about a Jewish family, but the trad exterior slowly begins to yield Popper's distinctive comic voice as this first episode warms up. Superb stuff.

What a rarity: a sitcom that isn't black-hearted, cruel, vituperative, mean-spirited or blushingly filthy. Friday Night Comedy is rather sweet, which might sound like the kiss of death for a comedy, but luckily it's funny, too. Not gut-bustingly funny, but enough to make you want to return. Writer Robert Popper (he also acts, produces and is a prank phone-caller of considerable renown) has adapted his own early family life to bring us the Goodmans; mum, dad and two grown-up kids, who all gather round the dinner table every Friday night. Mum (splendid Tamsin Greig) is sweetly daffy and obsessed by MasterChef, while dad (Paul Ritter) is a bit bonkers, and has a bizarre obsession with his yellowing collection of ancient New Scientist magazines. It's all a bit Mike Leigh, only funnier.

If you liked the cleverly played-out dysfunctionality of Grandma's House, you'll enjoy this new comedy. Newcomer Jack Rosenthal and Inbetweeners star Simon Bird play brothers joining their parents (Tamsin Greig and Paul Ritter) at the family home for dinner. The evening descends into enjoyable farce as a man unexpectedly comes to collect the sofa bed, Dad figures out how to avoid chucking away his New Scientists and a weird neighbour (Green Wing's Mark Heap) keeps popping in to use the loo.
