Thus, Stuart Fails to Save the Universe was born. I stumbled across it a week ago. Of course, I had to see what this American science fiction comedy TV series created by Lorre, Zak Penn, and Bill Pradyit was all about.
Stuart Fails to Save the Universe is the third spinoff of The Big Bang—first was Young Sheldon then Georgie and Mandy's First Marriage, and now Stuart's series.
This latest entry in The Big Bang franchise premiered on HBO Max on July 23, 2026.
It's premise? Stuart Bloom accidentally damaged a device created by Sheldon Cooper, Leonard Hofstadter and Howard Wolowitz.
Therefore, Stuart must prevent a "multiverse Armageddon" and save the Universe by traveling through various alternate realities to change his own reality. In each new reality, he encounters friends and acquaintances from his own reality.
To be honest, this series seems like a love poem to The Big Bang, because it brings back the quirky characters from that series. It's like having a family reunion with all the weird cousins showing up. Look at the Cast below, and you'll see what I mean.MAIN CHARACTERSKevin Sussman as Stuart Bloom and as Alternate Stuart Bloom.
Lauren Lapkus as Denise, Stuart's true love.

WHY WATCH
If you're a Big Bang fan, I don't have to tell you why you watch. If you're not a fan, watch because it's weird, the episodes are short, and each episode gets better than the previous. Watch because the title creds alone are funny, creative, and different—they are an inside joke aimed at the entire audience that tries to skip over the credits.
The first 3 episodes I watched are: Episode 1, Spoiler: Gary Dies; Episode 2, Spoiler: Zack's In This One; and Episode 3: Bert's Magic. A new episode will drop every week.MY THOUGHTS
If I weren't a fan of the original series, I don't know that I'd have watched the second episode. Once Barry Kripke, played by the talented John Ross Bowie, shows up, I was hooked.
Every scene with Kripke in Episode 2 is a belly laugh, side-splitter. If you've been looking for something different, give this a try. Watch the first 3 episodes, and I think you'll want to watch the rest.
TAKEAWAY TRUTH
Like most streaming series, the future of Stuart Fails to Save the Universe depends on the audience numbers. I don't know if this series has enough promise to carry what seems like a one-joke premise into the future, but if anyone can do it, Chuck Lorre can.
