For nerd culture — which has become much more mainstream over the past dozen years or so — this is definitely a time of change. And loss. HBO’s Game of Thrones is coming to an end. The Marvel Cinematic Universe is closing a significant chapter with Avenges: Endgame and June’s Spider-Man: Far From Home. In the world of Star Wars, the saga that began in 1977 is wrapping up with December’s The Rise of Skywalker. And, now, we’ve just said goodbye to The Big Bang Theory, which finished as the longest-running multi-camera sitcom in history after 12 years and 279 episodes (and before you ask, Cheers “only” had 275), sending Jim Parsons, Johnny Galecki, Kaley Cuoco and the rest of the cast their separate ways.

The question in the case of Big Bang, of course, is how’d they do? Unlike other shows that seem overwhelmed with the pressure of capping things off (we’re talking to you, Seinfeld) or prefer ambiguity (The Sopranos), the creators of The Big Bang Theory elected to wrap up some storylines while setting in motion others that we’ll never see but can only imagine, all along allowing the characters to evolve and never losing sight of its primary goal: to make us laugh, and, in this case, shed a few tears.

Scroll down for more. But beware, spoilers. You’ve been warned! Seriously. If you haven’t seen it, stop reading. OK, this is on you, then.
