I get that the series went beyond what McGoohan had in mind for stories (i.e. number of episodes), but surely something would have been possible beyond the annoying tripe we ended up with.
That's the big question. McGoohan had realized he had written himself into a corner (just like the TNG producers for BoBW or the producers of LOST). He got himself a couple of sandwiches, whiskey and cigarettes and locked himself into the trailer the night before shooting.
He hated the James Bond concept (he turned down to play 007 which then passed to Sean Connery) and the one thing he was most assuredly
not to give audiences was a Number One villain like Blofeld who had just gotten featured in YOU ONLY LIVE TWICE (
Fallout has several moments that look like his vitriolic reaction to the latest Bond film, then

).
No matter how bizzarre, weird or grotesque the final episode was, it had the correct message (the worst enemy you could possibly encounter is yourself) - and a rather bold one coming from a devout Catholic, I should add (don't blame the devil when the one to actually blame is yourself).
The episode does look like the
antithesis to Awesome Wells' adaptation of Franz Kafka's
The Trial and stays somewhat faithful to the original statement of the main protagonist, Number Six: "I will not be pushed, filed, stamped, indexed, debriefed or numbered!" Same goes for his series that refuses up to this day to be filed, indexed or numbered (which also applies to the major production being filmed next door: 2001), I find this symmetry rather fascinating.
Looking back, it made These Are the Voyages look like All Good Things by comparison!
I couldn't disagree more. What was the message or statement? That Riker needed a history lesson to make up his mind whether to tell Captain Picard what really happened on the
Pegasus (which ne never did because he was under Pressman's orders not to do so

).
Some audiences like their finales to be straightforward and self-explanatory, others - like me - don't mind a finale which retains an obvious ambiguity and offers multiple interpretations (I'm talking PRISONER, not LOST!).
The intriguing thing about the series up to this day for me is that it remains inconclusive whether the Village is run by the "other side" (to extract information from Number Six), by his own people (to see if they can accept his resignation and how he would hold up under pressure) or some kind of twisted alien experiment (ballon-like "Rovers").
