His Dark Materials was billed as the BBC's biggest drama ever and is said to have cost £50million.
The eagerly-anticipated adaptation of Philip Pullman's beloved trilogy of novels made its debut on BBC One last night (3.11.19) but there was a mixed reaction from viewers.
The epic fantasy tale follows the coming of age of two children, Lyra Belacqua and Will Parry, as they wander through a series of parallel universes.
In the story, human souls take animal forms known as 'daemons' said to represent their owner.
His Dark Materials was absolutely superb. A magnificent adaptation.
During her search for a kidnapped friend, Lyra uncovers a sinister plot involving stolen children and a mysterious phenomenon called Dust.
The eight-part series also boasts an all-star cast including James McAvoy, Ruth Wilson, David Suchet and Helen McCrory.
The drama, which debuted on BBC One at 8pm, thrilled many viewers, who took to Twitter to voice their delight at the adaptation.
One viewer said: "His Dark Materials was absolutely superb. A magnificent adaptation.
"Perfect Sunday night TV.
"Can't wait for episode two."
But as much as people loved the first episode, there were others who weren't so keen.
One viewer said: "On a not so fun note, His Dark Materials premiere was kinda awful.
"Dialogue is choppy, the pacing and world-building feels incredibly off in hard-to-explain ways, and it all around just didn't work well."
