Travelling across the generation gap can be tediously repetitive

Travelling with young people can be a nightmareconstant requests for food, running out of charge for one of the myriad devices they carry with them, the never-ending call of 'are we nearly there yet?'

- Philip Cunnington on Worlds Apart

But Channel 4's new reality show Worlds Apart (Channel 4, Tuesday, 9.15pm) made the whole business look childishly easy, especially as much of the actual travelling had been excised from this week's first episode.

Six youngsters and six oldsters had been magically whisked to Tokyo, where they first had to find each other, and then had to complete a task to win coins - the teams with fewest coins at the end would be heading home.

To be honest, watching 12 people wander around a busy city was not the most transfixing hour of television you could ever watch.

Each part between the ad breaks saw two pairs - one youngster with one oldster - get directed around the city to find a location where they did the task.
