The past few years have been like a sitcom desert in British TV land. I seriously can’t remember one sitcom I’ve actively made an effort to watch from start to finish. To my surprise, Gavin and Stacey has filled that void. The first series passed me by - mainly because I was just so fed up with sitcoms and refused to watch any – but I decided to take a punt on series two. I’m so glad I did. It’s warm, makes you smile from start to finish and has a hint of subversion thrown into the mix. Last night’s episode, the series’ penultimate one, was just the same. It just keeps on coming week after week.

The story sort of came full circle last night, with Stacey moving back to Barry Island and Gavin back in Essex. This is how Gavin and Stacey first started their courting.

Anyway, the beauty of this show isn’t about the Gavin and Stacey characters, it’s about the wonderful ensemble cast around them. And, although there are a few storylines, it’s more about finding comedy in the mundane and every day.

Last night, Gavin’s mum and dad were fretting about a new mobile phone mast that was to be erected 68ft away from the house. Pam (Alison Steadman) was planning to stage a silent protest when the mobile phone company came to plant it. She asked her husband Mick, when he queried her involvement in the protest, whether he would like to contract “brain cancer or tumour brains”. In the same sentence she moaned about the mobile phone coverage in the area.

Then there was Uncle Bryn (Rob Brydon). He’s great. He was trying to cheer Stacey up, who had not moved from her makeshift bed on the sofa all morning. He turned the TV off and told her excitedly about a new website he had found, The You Tube, and how he had watched the entire first series of Desperate Housewives on it.

Gavin and Stacey is full of these little moments. Nessa (the peerless Ruth Jones) earning some money as a silver-painted human statue was great, and her explaining to Stacey what it was like going out with John Prescott (“I had a cracking social life. Many a night we’d have David Blunkett and his bitch round for dinner”) was also priceless.

The story last night saw Bryn and Nessa take Stacey out to the bingo to try and take her mind off things. Smithy, meanwhile, had the bright idea of taking Gavin and the boys to a Foam Night at the local club in an attempt to cheer him up. Despite their best intentons, it wasn’t working – Gavin and Stacey were pining for each other.

So another episode, another winner and easily the best comedy series currently on television.
