Young Sheldon already feels like a distant memory, but viewing figures suggest Georgie & Mandy might have more to it than first thought.

Sheldon isn't in Georgie & Mandy's First Marriage's premiere, and its best Young Sheldon pilot's reference makes his absence more obvious.

"Georgie and Mandy's First Marriage" pays tribute to "Young Sheldon's" most tragic moment in a way that's slightly jarring given the spin-off's lighter tone.

Ana Dumaraog of ScreenRant gives it a 9 out of 10, noting that the first two episodes are surprisingly emotional despite the show’s switch to multi-cam. Georgie & Mandy’s First Marriage is a worthy replacement for Young Sheldon, Dumaraog says:

"I like laughin' shows," Georgie Cooper (Montana Jordan) declares in the opening scene of "Georgie & Mandy's First Marriage." "Some shows you can hear people laughin', and some you can't. ‘The Wonder Years' - no one's laughin'.

Goodbye young Sheldon Cooper, hello somewhat grown-up Georgie Cooper. 'Georgie & Mandy's First Marriage' premieres tonight.

The new series, “Georgie & Mandy’s First Marriage” stars Sheldon’s older brother, his wife and their daughter.

The premiere episode of "Georgie & Mandy's First Marriage" is here, and it confirms an important change that was last seen on "The Big Bang Theory."

At last, Young Sheldon Season 7 is available to binge. Hours ahead of the debut of the CBS sequel series Georgie & Mandy’s First Marriage (airing Thursday at 8/7c), all 14 episodes from Young Sheldon’s farewell run are now live on the Warner Bros.
