Rab C. NesbittOne of the best-loved characters in comedy returns to screens as Gregor Fisher reprises the role of Glaswegian alcoholic, Rab C Nesbitt.

But the last ten years have seen some surprising changes in our beloved Rab.

He's ditched the drink, found religion, discovered lattes and even located the cooker. The training shoes and the head bandage remain but Rab is a new man. "I can get high on a sunset. My heart skips with joy on hearing a lark," he insists before bursting into song. Erm, right.

Rab isn't the only one to have cleaned up his act. Rab's wife, Mary Doll, now runs a thriving cleaning company with her old pal, Ella Cotter. Meanwhile, their eldest son, Gash, has moved out of the family home, turned vegetarian and set up in business with his new wife, Lorna.

But do these changes in the Nesbitt household mean a change in humour for the much loved-sitcom?

Dark, crude and wonderfully politically incorrect, this one-off special holds true to the show's original comedy. Rab's raging temper hasn't cooled much over the past decade; he's still got issues and there's plenty he wants to get off his string-vested chest.

Modern rip-offs, the media, and the state of the nation in the 21st century all get attacked with Rab's characteristic vitriol and a large dose of sarcasm as he struggles to resist the demon drink in the run-up to Christmas. But can he manage it? If he doesn't, the old Nesbitt we know and love may well be back before the turkey's been stuffed.

It's always a joy to see classic TV shows return to screens, but unfortunately in this case the genuine laughs are few and far between. Perhaps we would all be better off if the greats were allowed to end on a high.
