‘Stuart Fails to Save the Universe’ Review: The Big Bang Theory Expands Into Science Fiction

A necessary disclaimer before beginning this review: I never really watched The Big Bang Theory. I vaguely remember catching a few episodes here and there, perhaps during its first season or around that period, a long time ago (we are talking about a series that premiered in 2007), but I know its characters only in the broadest sense and have never been particularly familiar with the world they inhabit. In other words, the world of Stuart Fails to Save the Universe was completely foreign to me — at least on paper. That said, the characters are built around such recognizable archetypes that it does not take long to understand who they are and how they function.

This matters because Stuart Fails to Save the Universe is, after all, another spin-off from The Big Bang Theory, this time focusing on characters who were secondary figures in the original sitcom. At the center is Stuart Bloom (Kevin Sussman), the owner of The Comic Center of Pasadena, the comic-book store where the original show’s characters often spent time. The main difference between the two series is, at least initially, their genre and format: while The Big Bang Theory was a traditional multi-camera sitcom built around the rhythms of American television comedy, Stuart Fails to Save the Universe is closer to a science-fiction comedy, abandoning the classic live-audience sitcom structure.

Beyond the cameos, references, and connections to its parent series, Stuart Fails to Save the Universe does not require much previous knowledge to establish its own world. It works surprisingly well for newcomers. The story follows four friends (that is perhaps a generous description) who come together at the comic-book store and discover, after experimenting with a device capable of traveling across the multiverse, that their reality has somehow been altered. The world they knew is no longer the same, and they must try —with very limited success— to return to the original one, jumping from episode to episode through parallel realities where familiar elements have been transformed.

That premise allows creators Chuck Lorre and Bill Prady —alongside sci-fi specialist Zak Penn, co-writer of Ready Player One— to move the familiar territory of The Big Bang Theory into a space that combines traditional sitcom humor with science-fiction concepts. These intense, socially awkward nerds attempt to repair their device and travel toward random universes, despite barely understanding how the primitive machine actually works. They repeatedly land in realities that are less appealing than the one they left behind. They start in a post-apocalyptic world, but the problems they encounter in each new universe make them desperate to continue searching for the next one.

Alongside the shy and anxious Stuart are Bert Kibbler (Brian Posehn), a highly eccentric geologist, and Barry Kripke (John Ross Bowie), the Caltech physicist known for his unusual speech pattern and difficult personality. They are soon joined by Denise (Lauren Lapkus), the comic-book store employee and Stuart’s former romantic partner from the original series. Together, the four travel through different versions of reality, each with its own variations and surprises — most of which are better left undiscovered here. One exception comes in the fourth episode, when Stuart finds himself in a psychiatric hospital. As he explains his story to the therapist treating him, it becomes increasingly clear that perhaps this is exactly where not only Stuart but the entire group belongs.

The series is short, light, and generally entertaining, although it begins to feel repetitive during its second half. Its final episode, however, introduces an intriguing narrative twist that clearly leaves the door open for the second season everyone expects will come. Among the funniest elements of Stuart Fails to Save the Universe are two things that exist somewhat outside the fictional world of the show: its opening credits, which playfully interact with the audience, and Chuck Lorre’s traditional vanity cards — those brief comments, jokes, and observations that appear after the credits at the end of each episode. It is worth staying until the very end (do not hit “skip”), pausing them, and reading them. They are often funnier than some of the episodes themselves.

Stuart Fails to Save the Universe will certainly appeal to fans of The Big Bang Theory — as well as viewers who followed its prequel Young Sheldon or its other spin-off Georgie & Mandy’s First Marriage — by reconnecting them with familiar characters and expanding the franchise’s universe. But it could also introduce the series to newcomers who might decide to revisit its original 12-season, 279-episode run, one of the last traditional sitcoms to become a true mass-audience phenomenon. At its peak, The Big Bang Theory ranked among television’s biggest comedies, dominating the sitcom landscape for years. If this new chapter allows Chuck Lorre’s franchise to regain visibility with both longtime fans and a younger audience discovering it for the first time, it will have succeeded on more than one universe. Or all of them.
