ITV's ambitious new entertainment format The Nightly Show has made its big debut - and was immediately slammed on Twitter.
The new show is the broadcaster's attempt to replicate the success of late-night telly in the US - particularly James Corden's The Late Late Show, which is a viral sensation thanks to its Carpool Karaoke segment.
A different famous face will guest host each week, with Britain's Got Talent judge David Walliams taking the reins for its launch week.
His skits for the first episode included a parody of the Oscars drama that saw La La Land mistakenly announced as the winner of Moonlight's Best Picture award.
David also appeared in a mock press conference with President Donald Trump.
As you might expect, many viewers didn't like what they were seeing and took to social media to complain.
Some viewers thought the first guests, Martin Clunes and Nina Conti, weren't big enough names to launch the show with.
I turned to the Nightly Show to see that their big launch night guest was... Martin Clunes? Nice funny bloke, but - really?

Let me get this straight. The first guest on a new nightly chat show ITV are desperately hoping will be a big success is Martin Clunes.

Others were angry that ITV has moved the News At Ten to 10.30pm to make way for its big experiment.
ITV We do not want the nightly show,please stop messing with our news at ten.

Loads seemed to think The Nightly Show was just rather rubbish.
How dreadful is the Nightly Show? Yes that's right bloody awful.

Just a thought. But maybe ITV should replace The Nightly Show with the news. It's funnier.

However, not all the reaction was negative.

In fairness, The Nightly Show is an ambitious project, and one that will take a while to find its groove.
ITV has certainly given it plenty time, as it will air every weeknight at 10.00pm for the next eight weeks.
If The Nightly Show does prove a success, it's likely to become a permanent fixture in the schedules.
Other names lined up as presenters include John Bishop, Gordon Ramsay and Mel and Sue. Meanwhile, guests appearing later this week include Kim Cattrall and the coaches from The Voice UK.
