Pick of the Day
Avenue 5, 10.00pm, Sky One & NOW TV
With Veep gone, here's the ideal replacement and yet another creative feather in the cap of that show's creator Armando Iannucci, who also has the superb The Personal History of David Copperfield in cinemas this weekend.
It's a space tourism comedy set 40 years into the future when a trip throughout the solar system is on everyone's bucket list.
Hugh Laurie stars as Captain of the luxury space cruise liner Avenue 5, Ryan Clark. On board you can expect a first class experience, with gourmet buffets, a spa, yoga classes and an observation deck to watch the planets and stars as you fly past.
As the series begins, Avenue 5’s eight-week journey around Saturn is underway and everything seems optimal. But when the ship suddenly encounters technical difficulties, it’s up to Ryan and his crew to calm the disgruntled passengers and deal with the unexpected events on board.

In this finale, the lambs have become much-loved family members, but Pam and Lou feel committed to remaining as meat eaters.

Good Omens, 9.00pm, BBC Two
It took me a while to get into last week's opening episode of Neil Gaiman’s quirky fantasy series – but once I did, it proved totally engrossing.
Based on Gaiman's book with Terry Pratchett, this second episode sees Aziraphale and Crowley realise that they've been following the wrong boy for years, so they must now try to locate the real Antichrist.
The pair head back to Tadfield, to the old convent and site of the baby-swap, only to discover it no longer exists. As they head back, they cross paths with Anathema, and soon discover that she has lost Agnes Nutter's book.
