Pick of the day

Wanderlust, 9.00pm, BBC One

This new drama's been on the controversy carousel over the last few weeks, making all kind of claims and boasts about its sexual content.

So – as the continuity announcers say – expect strong adult themes from the start.

After years of marriage, therapist Joy (Toni Collette) and Alan Richards (Steven Mackintosh) find themselves in a sexual cul-de-sac.

Joy is trying to find a way to keep her spark with her husband, following a cycling accident which has put their sex life on hold. Suddenly they find themselves drawn to new people, and both are tempted to make the ultimate indiscretion.

With their marriage in crisis Joy comes up with an audacious, unorthodox, but potentially brilliant proposal that will surely have huge ramifications for their future . . .

McMafia, 10.15pm, RTÉ One

James Norton did a reasonably good James Bond audition here, but that's one of the few positives to be gleaned from this glossy-but-muddled drama about dodgy rich Russians throwing their weight around London.

When his family’s past brutally returns, Russian exile Alex Godman (Norton) gets drawn into the murky world of international crime.

Having spent his life trying to escape the shadow of his father’s criminal past and running a successful London hedge fund, he suddenly finds himself having to protect his family and fight for all he has worked for.

Give me the Kardashians over royalty anytime. At least they work for a living.

Here's a new documentary about Harry Windsor and Meghan Markle’s first few months together as newlyweds. For obsessives only, I'd imagine.

Ending Tonight

Shades of Blue, 10.00pm, Sky Witness & NOW TV

It’s the last-ever episode of the daft police drama starring Jennifer Lopez as Harly Santos, a hard-pushed female cop whose hair is never less than impeccably coiffured while she roots out dirty cops.

As Harlee’s story comes to a crashing end, she faces a police commission as Wozniak and the crew scramble to help her from the outside.

The Joy of AI, 10.00pm, BBC Four

The 'Joy of . . .' strand wraps up with professor Jim al-Khalili taking what's promised to be a sharp-witted and refreshingly optimistic look at how we have created machines that can simulate, augment, and even outperform the human mind - and why we should not let this spook us.
