The Big Bang Theory fans have been left seriously confused after the ‘absolutely insane’ plot of the upcoming spin-off was finally confirmed. The original sitcom ended in 2019 after 12 years on our screens, but sparked two separate prequel shows – Young Sheldon and George & Mandy’s First Marriage.

Kevin Sussman returns as Stuart in a sci-fi adventure that Chuck Lorre describes as something the original characters "would have loved, hated, and argued about."

But The Big Bang Theory obviously had a crap-ton of fans; you don’t get to 12 seasons and two spin-offs (the recently concluded Young Sheldon and Georgie & Mandy’s First Marriage, which has a second season coming) without some ironclad popularity in place.
