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:

Georgie & Mandy’s First Marriage is the third in The Big Bang Theory franchise, and is a sequel to and spin-off of Young Sheldon. The series focuses on young parents Georgie Cooper (Montana Jordan) and Mandy McAllister (Emily Osment) who got married in Season 7 of Young Sheldon.

When Young Sheldon was nearing its end, I was one of the first to say I needed to see Mandy's parents, Jim and Audrey McAllister, be a part of the main cast of Georgie & Mandy's First Marriage. I'm happy to say I thought that Will Sasso and Rachel Bay Jones crushed it in their roles.
