The Big Bang Theory's Newest Spinoff Officially Avoids Young Sheldon's Big Problem

Published Sep 19, 2026, 2:15 PM EDT Laura Hurley has been writing about the entertainment industry for more than twelve years, after a decade as a content producer and editor at CinemaBlend after writing for WhatCulture and Examiner. Attending events like SCAD TVfest and San Diego Comic-Con over the course of her career, she has been immersed in the world of network, streaming, and cable TV. The Big Bang Theory TV universe has been going strong ever since the original series became a hit for CBS in 2007, but the state of the franchise now is nearly unrecognizable from how it started. While network sitcom Georgie & Mandy's First Marriage carries on the legacy of Sheldon Cooper in CBS' 2026 fall schedule, the franchise's first streaming spinoff has already created comedy gold that avoids Young Sheldon's biggest problem. Officially a hit on HBO Max, Stuart Fails to Save the Universe has gone in bold new directions, and none of them cause issues for the rest of the franchise. HBO renewed the comedy for a second season before the first even wrapped up. That alone was a big win for Chuck Lorre and the rest of the team behind the comedy, since this series was by far the riskiest of the three Big Bang Theory spinoffs so far. Young Sheldon was all but guaranteed to become a success. It launched on CBS before TBBT had even concluded, and focused on the most popular character in the original show. Georgie & Mandy's First Marriage is more or less a multi-camera continuation of Young Sheldon, also on CBS, and it returns to The Big Bang Theory format of recording in front of a live studio audience. Stuart Fails to Save the Universe, however, is the franchise's first streaming show, and it doesn't have the kind of star power to give the sense that it would be an automatic hit. Even though Stuart (Kevin Sussman), Denise (Lauren Lapkus), Bert Kibbler (Brian Posehn), and Barry Kripke (John Ross Bowie) are all familiar faces from TBBT, none were among the main stars. The show's premise is also much more sci-fi than slapstick, with Stuart trying to restore reality throughout the multiverse after breaking a device built by Sheldon and Leonard. Stuart Fails to Save the Universe's season 2 renewal likely means that its first season is unlikely to resolve this apocalyptic scenario. But Stuart's ongoing failures are a win for the viewers enjoying this fresh take on The Big Bang Theory universe. Young Sheldon Destroyed TBBT's Continuity, But Stuart's Spinoff Is Canon-Immune Credit: MovieStillsDB Young Sheldon should have had the easiest job of expanding the franchise, and not just because it premiered before The Big Bang Theory ended in 2019. The original show had already set up the blueprint for Sheldon's journey. Jim Parsons' character established major turning points from his childhood on TBBT, while still leaving plenty of room for the spinoff to flesh out his story. Sheldon's relationships with his various family members (and memories of his dad) showed where he had to end up, and Young Sheldon had the freedom to fill in all the blanks without destroying the continuity. Instead, Young Sheldon increasingly began to diverge from Sheldon Cooper's lore and completely broke continuity with The Big Bang Theory, particularly with regard to the timeline and the characterization of his dad. Some of the most highly-anticipated moments that fans expected from the prequel never happened, due to Young Sheldon going overboard to redeem George Sr. from how Sheldon described him as an adult. With The Big Bang Theory still going for another two seasons after Young Sheldon premiered, the continuity errors felt increasingly egregious. Stuart Fails to Save the Universe completely avoids the Big Bang continuity issue. Not only is there considerably more freedom in expanding the stories of characters like Stuart and Kripke, whose backstories were largely blank, but the very premise of the show involves alternate universes with different versions of the same characters. Stuart makes the most of the freedom to go in some wild directions to deliver laughs, rather than retread old ground or rewrite canon like Young Sheldon did. The alternate realities also made it possible for Stuart Fails to Save the Universe to incorporate the biggest stars from The Big Bang Theory without contradicting anything else in the franchise. The first season already delivered alternate versions of Penny (Kaley Cuoco), Amy Farrah Fowler (Mayim Bialik), Raj (Kunal Nayyar), Bernadette (Melissa Rauch), and even Wil Wheaton (Wil Wheaton), and it didn't matter that the characters were totally different from their portrayals on The Big Bang Theory. Stuart Fails To Save The Universe Is The Big Bang Theory's Best Spinoff Yet Image courtesy of HBO Max On the whole, Stuart Fails to Save the Universe succeeds in several ways that Young Sheldon and Georgie & Mandy haven't in the years since The Big Bang Theory ended. For one, Kevin Sussman's comedy is the first spinoff in the franchise that really can be enjoyed by newcomers who haven't already watched any (or all) of the earlier series. Sure, the cameos from Kaley Cuoco, Kunal Nayyar, and the others are treats for fans of TBBT, but viewers don't need an encyclopedic knowledge of lore to jump into the wild sci-fi ride of Stuart Fails to Save the Universe. It's also the first spinoff to prove that the franchise can thrive by taking major risks, and stands as the only show in the TV universe so far to release exclusively on streaming. Stuart makes the most of the freedom that comes from releasing on a platform with fewer constraints than network TV, and HBO Max is a much stronger platform for the series than CBS would have been. Stuart Fails to Save the Universe doesn't just feel like more of the same. The added perk that the series doesn't contradict the Big Bang Theory timeline means that the franchise's most unique spinoff actually fits the best with the original series out of the three. The season 1 finale will release on September 24, and then the wait begins for season 2.
