Well after the series signed off in 2019, The Big Bang Theory remains one of television's most successful sitcoms, even coming in as 2024's "most-binged title" in streaming. While some elements of the show haven't aged well, it's hard to deny that the series consistently delivered downright hilarious moments in its 12-season run. If there's one fault to be had, it's this: there's a sameness to which characters interact with one another. It's either a story that embraces the entire gang, an episode where the guys are together in one storyline and the girls in another, or an episode that switches between the paired-off couples.
