Sunshine

If some people see life as a comedy, while others insist it is a tragedy, then the writing team of Craig Cash and Phil Mealey must fall into the first camp. They just can't help themselves from seeing the funny side of the most dire situations. They would probably get the giggles at a funeral.

And while that's better than going through life being a total misery, that could explain why this series about the very unfunny problem of gambling addiction is looking a bit unsteady on its pins as it lurches drunkenly from the sweet to the sour.

Having said that, if you don't get a little seasick from the shifting tone there's plenty to enjoy here - especially in the cockle-warming friendship between little Joe and his grandad George. And also, of course, in Steve Coogan's central performance as eternal loser Bing Crosby.

Usually dramas about addiction are a misery to watch, but this one manages to remain upbeat in spite of its subject matter. Having already been thrown out of the house by his long-suffering wife, Steve Coogan's inveterate gambler still can't kick the habit. Yet he remains as funny and engaging as ever, refusing to face up to his problem and believing, like all gamblers, that he can win his way out of trouble with a streak of good fortune. My wife thinks I can't turn over a new leaf, and I'm going to show her that I can. Do you want me to put a couple of quid on it for you? Sunshine doesn't avoid the nasty stuff, but it is balanced by an abundance of warmth, good humour and humanity.
