Spoilers below for the third episode of Stuart Fails to Save the Universe, so be warned if you haven't yet streamed it via HBO Max subscription.
When it comes to wacky AF sci-fi storytelling, Stuart Fails to Save the Universe may have a total lock on the 2026 TV schedule, at least for the moment. The HBO Max comedy’s weekly jaunts to alternate dimensions is the kind of concept that could theoretically last forever, assuming the creative team keeps finding ways to make it work. Such as having former Big Bang Theory stars appearing as wildly different and possibly demonic iterations of their beloved characters, and then killing (some of) them off.
