The Big Bang Theory premiered nearly two decades ago and became a network TV phenomenon.
While the sitcom ended in 2019, its universe has only grown with several spin-offs. Its newest expansion, Stuart Fails to Save the Universe, may be the franchise’s strangest swing yet.
On April 27, HBO Max unveiled a first look at the spin-off, set to debut later this year, alongside plot details that left netizens baffled by a premise far removed from the original show’s relatively grounded tone.

As the title suggests, Stuart Fails to Save the Universe will center on Stuart Bloom, played by Kevin Sussman in the original series.
Introduced as a recurring character during the sitcom’s second season, Stuart is a quirky, socially inept comic book store owner. In the spin-off, he is tasked with restoring reality after he breaks a device built by Sheldon and Leonard.
The accident triggers a multiverse Armageddon, forcing Stuart to enlist Denise, Bert, and Barry Kripke to save their universe from certain doom.
Unlike earlier spin-offs focused on family-friendly storytelling, the new series embraces the sci-fi tropes that The Big Bang Theory mostly parodied.
Original show’s creators, Chuck Lorre and Bill Prady, serve as head writers on the spin-off, alongside Zak Penn.

The plot details for Stuart Fails to Save the Universe surprised even the most diehard fans of the original series, who weren’t expecting such a drastic spin on the beloved sitcom’s world (or multiverse).
On X, several users expressed their bewilderment at the new spin-off sci-fi premise. Others were surprised the franchise was getting yet another spin-off after Georgie & Mandy’s First Marriage, which already felt far removed from the original.

“The more I read. The more confused I got,” one user commented.
Another wrote, “Absolutely no one asked for the Sheldon Cinematic Universe yet here we are.”
“This is so far off from what the big bang theory was lol I doubt this is gonna be good in any way,” a third person said.
Some fans argued that the streaming service was banking on nostalgia and questioned whether a spin-off focusing on several side characters would even find an audience. The rest were intrigued by the wild premise and were interested in streaming the new series once it premieres this summer.
