Honor what you’ve already done. However a show ends, it shouldn’t come completely out of left field, or worse, undermine everything that viewers have enjoyed leading up to it. Having a key player do something totally out of character might be surprising — an attribute writers tend to prize — but it risks selling out what they’ve spent years establishing.
Cryptic can be fine, but closure is better. Ultimately, leaving the door open for the viewer to conjure or interpret their own ending feels like a copout — like a book without a last chapter. It’s your story, not ours, so finish it. And if nobody can understand what happened without reading your postmortem interviews, you’ve messed up.
Be quick, but don’t hurry. OK, this is stolen from the legendary basketball coach John Wooden’s Pyramid of Success, but it applies equally well to television. There’s a tendency to raise through plots and characters that can easily feel rushed and forced. Given the luxury of having time to build to an end, don’t wait till you can see the finish line before turning on the jets.
It’s not necessary to tie up every loose end. Especially for large ensemble shows, it can easily become problematic trying to provide an exclamation point for every character. Think about what’s fundamental to the show, and wrap that up. Dangling threads can be irritating, but tying them all off only works if it’s organic to the larger payoff.
Treat it like it’s over, even if it’s not really over. Given the value invested in these properties, the odds of studios letting them lie completely dormant are slim, what with all the reboots, spinoffs and revivals. Don’t worry about that. If someone decides five years from now to do “The Bigger Bang Theory” or “Daughter of Dragons,” that’s their headache.
Accept that you can’t please everybody. It’s a given that there will be second guessing, in part because many viewers and critics tend to concoct their own scenarios about what would be an appropriate finale. Take it as a given that every twist will be debated and analyzed, then debated some more for a second wave of web traffic.
In other words, clearly tell the story you set out to tell, then don’t read the comments.
