‘Stuart Fails To Save The Universe’ Review: A Bizarro ‘Big Bang Theory’ Spin-Off

The Big Bang Theory remains one of the most significant American mainstream comedies of the 21st century. Its legacy, which chronicled the lives of four socially awkward scientists, has proven remarkably durable, spawning the long-running prequel Young Sheldon and the ongoing sequel Georgie & Mandy’s First Marriage. However, the latest expansion, Stuart Fails To Save The Universe, takes a decidedly more experimental path.

Helmed by series creators Chuck Lorre and Bill Prady alongside screenwriter Zak Penn, the show shifts the focus to secondary characters, specifically the perpetually down-on-his-luck comic book store owner Stuart, played by Kevin Sussman. Rather than a traditional sitcom, this spin-off embraces a high-concept, dimension-hopping narrative that sees Stuart grappling with cosmic failures.

A Cosmic Shift in Pasadena

The series begins in the familiar setting of Pasadena, but with a surreal twist. The local comic shop now features a literal dimensional rift on the floor, and the supporting cast—including Brian Posehn as the geologist Bert—finds themselves navigating an apocalyptic alternate reality. In this version of events, John Ross Bowie’s character, Barry Kripke, has ascended to the role of “Lord Kripke,” wielding power over the remnants of society.

The narrative kicks into gear when a version of Stuart from our own dimension arrives to warn his doppelgänger that the original gang’s experiments with quantum entanglement have fractured reality. It is a premise that allows the show to lean heavily into sci-fi tropes, complete with action-hero sequences set to the Beastie Boys‘ ‘Sabotage’.

A Refreshing Genre Mash-up

By moving away from the traditional multi-camera sitcom format, Stuart Fails To Save The Universe offers a refreshing take on the franchise. The inclusion of Lauren Lapkus as Denise adds a necessary grounding element to the chaos as the characters traverse various realities, referencing everything from The Matrix to classic fantasy tropes. The show manages to maintain the spirit of the original series while effectively deconstructing it.

While the series is packed with guest appearances and nods to the source material, it succeeds primarily because it is willing to be weird. It is a bold, imaginative expansion that feels like a project the original characters themselves might have conceptualized. As the show’s protagonist aptly notes, “Shit just got weird.”

‘Stuart Fails To Save The Universe’ premieres July 23 on HBO Max, with new episodes released weekly.
