The best things to watch on TV tonight, Wednesday 1 December, 2021
Paddy and Christine McGuinness: Our Family and Autism - BBC One - 9pm
The McGuinnesses are always happy to raise awareness of what it's like to parent children with autism, but this documentary is a particularly unflinching look at the challenges they face.
All three of the couple's children have been diagnosed with autism, and recently Christine herself, too.
Sharing honest and unfiltered views of what their family life is like, they also meet others in the same situation and talk about their changing feelings on the diagnoses.
Universe - BBC Two - 9pm
It's the final episode in the series and this time Professor Brian Cox is telling us all about how the universe came to be.
With a spectacular computer graphics representation of the Big Bang, it kicks off an episode of ponderings on how our world was able to support life.
Dexter: New Blood - Sky Atlantic - 9pm
The rebooted series about the secret serial killer continues with Dexter's struggle to restart his life in a small town.
By now, we know that Dexter has completely unsurprisingly given into his urges again, and tonight his latest victim's father makes a shock announcement.
I'm A Celebrity...Get Me Out Of Here! - ITV - 9pm
If last night's episode was a bit of a disappointment on the lack of drama, tonight's update from camp should rectify that.
We finally get to see what happened on the celebrities' big return to camp after Storm Arwen, while Naught Boy certainly didn't look pleased about being voted into another trial last night.
Grand Designs: House of the Year - Channel 4 - 9pm
The theme for tonight's batch of contenders is houses that solve a problem - and there are some incredibly innovative designs.
One house tackles the problem of being in a flood area, another deals with building in a remote environment, and others sidestep being overlooked, having budget constraints, and problems with converting agricultural buildings.
