10 Things That Must NEVER Happen In Doctor Who
7. An ACTUAL Ending
We've all been disappointed when beloved TV shows get revived and completely undo a perfect ending, right? Thankfully, Doctor Who will never do this, because there is no definitive ending built into the show's premise.
Barring extreme circumstances, the Doctor can't die, and instead regenerates into someone else, who takes off and has brand-new adventures. The Doctor isn't on some quest that has a clearly-defined endpoint, and when their companions leave, they just go somewhere else and pick up new ones.
When Doctor Who was taken off the air in 1989, the decision came so late that no clear ending was written, which was ultimately a godsend. Survival ended with the Seventh Doctor and Ace walking off into the sunset, looking forward to new adventures. Those new adventures ended up being a series of novels, and later, Big Finish audios, many of which influenced the next generation of Doctor Who.
Whether Doctor Who comes to an end next year or decades down the line, the ending has to be open-ended. As long as viewers know that the Doctor and the TARDIS are still out there, the adventure can live forever.
