One of tonight's pair of episodes deals with Christian snake catcher David Orin - though he prefers to call himself a "herper".

Much of this episode is spent following him around the woods as he hunts down snakes to then hold up to the camera and go "hey, look, it's a snake".

Of course they bite him sometimes, which seems to be part of his schtick.

The rest of his time seems to be spent praising the one and only Lord, Jesus Christ.

I couldn't help thinking if Jesus really appreciated the support, then maybe he'd get the snakes to stop biting David so much.

Brian Cox really, really likes space. And he likes NASA too.

Which is why he is so excited about getting exclusive access inside its Jet Propulsion Lab to watch the Mars rover Perseverance drive around on the surface of the red planet.

That's handy because his enthusiasm is rather infectious, making this documentary about whether the rover will find life on Mars interesting.

Because when we talk about life on Mars, we're not talking about Martians but microbes that would hint at past life there.

As far as I'm concerned it's a bit hard to muster up much excitement about the existence of tiny microbes, but Cox gets excited about it and so I did too.

Also, some of the shots of the surface of Mars do look pretty cool - even if they are bereft of aliens waving at the camera.

At first glance, there is something nice about this show where sons and daughters of single parents sign them up to appear in the hopes they find love.

They're worried about their parent and want them to find someone - what's not to like about that?

But, as is the nature of reality TV, the makers can't just run with that. Oh no. Reality TV so rarely does "nice".

What it much rather prefers is drama and conflict and so that search for love gets subsumed by the need to shake things up for the audience.

So we have the kids sitting in a room and spying on their parents in the house - though the mums and dads are unaware of this.

On top of that, the kids get to decide who their parent should go out on a date with. Maybe it's just me but I'd have figured that perhaps the parent might be the one who should decide who they date.

Also, people can be asked to leave the house at the end of an episode, and new mums and dads are brought in - with the obvious intent to create friction and jealousy should a newcomer try and move into someone else's territory.

Given this is a dating show for middle-aged people in a genre normally catering to 20-somethings, I'd hoped the approach might have been a bit more mature.

But that seems not to be the case.
