I don’t think when they established the 12 regenerations rule, that they realized the show would go on as long as it has. It’s been shown in the classic show that The Master got around these boundaries, and I don’t think there was any big plan leading up to the final incarnation, seeing as the rule was established nearly 40 years before the payoff. I don’t understand this complaint at all.
Yes but The Master didn’t get a whole new cycle, he body-swapped and continued to do it till the Doctor Who movie.
When they established the rule, no there wasn’t any big plan leading up to a finale and there never was but it was made very clear that the thirteenth incarnation would be the last and they continued to make the show up as it went along.
It was not his place to tackle the problem.
Then whose was it? I’m just glad it was addressed at all. The other solution would be to simply ignore it. Ending a popular show because an earlier episode decades earlier made a silly rule is simply nonsensical.
Whoever the writer would’ve been for the thirteenth incarnation is the one who would’ve tackled the problem, but they grew impatient with this and did it with Matt Smith who was as stated the Eleventh Doctor before they retconned it.
