One of TV’s wackiest and most innovative spinoffs recently debuted, and Stuart Fails to Save the Universe didn’t fail to win over most critics with its apocalypse-dodging multiversal adventures. Especially for a show like The Big Bang Theory, where the majority of the locations were apartments, Stuart's comic shop, the Caltech cafeteria, and other fairly limited-in-scope settings. Not the kind of place where characters are able to run around for longer than a second or two. According to Brian Posehn, however, that uptick in exertion was not part of the sales pitch from co-creator Chuck Lorre. Speaking of things that Stuart does that weren't possible on Big Bang — SPOILERS FOR ANYONE WHO DIDN'T WATCH THE PREMIERE YET — killing off OG characters like Kunal Nayyar's Raj, or at least alternate versions of OG characters.
