No, it isn't. But i find it curious you respond to my ruse rather than people with something to actually say on the topic.
Though i do wager that you have little comprehension of perceptions from 20 years ago, before i believe you were born......
Yeah, yeah.
Anyways, i'm going to do what I should have done AGES ago: spoon feed you all into understanding some of the so-called "plotholes" in
The Prestige.
Somebody previously asked why the Borden's both damaged their fingers. I would have thought it was obvious that these guys were so determined to keep their trick a secret that they couldn't risk somebody catching on. They simply wanted to remain CAUTIOUS. A bit drastic, I know, but if you accept the characters for who they are then you have to believe that these characters are willing to go to the extremes to preserve their legacy.
The point (fairly good one at that) about one of the Borden twins not telling the other Borden about the knot that was tied that ultimately lead to Julia's demise is left to one's (or lack of) imagination. Perhaps one of the Bordens was not brave enough to admit to even his own brother that you messed up? It's a plausible enough reason. Just because we're not shown specific scenes, does not mean that you can't interpret what might have happened off screen, innit?
You see, just because the film may unravel like a magic trick...all is revealed because it is a film, and not a magic trick itself, kids. Nolan shows us the magic-like structure, but one of the points was showing the uselessness of the secret to the trick, thus making the secret disappointing...as it should be.
This is further encapsulated when Borden says to that little boy "the secret impresses no-one; the trick you use it for, is EVERYTHING.
Oh, and those who say that the whole Tesla machine thing was "a rubbish" idea really has to be able to accept the sci-fi element towards the end to really let that slide. I and countless others do.
