Most movies are far removed from reality. But that is entirely the point.
The surest means to ruin the experience of watching any movie is to hold it to a ruthless standard of reality. This is because movies cater foremost to our sense of emotion. And past a point, reason, logic and facts stamp out emotion.
The key to enjoying a good movie is to suspend the gnawing sense of disbelief at its plot and instead contemplate its underlying message.
In a similar vein, we do a disservice to our epics and our myths by questioning their historical accuracy, for they aren’t designed to be historically accurate, but to appeal to our imagination and inspire us into action through their underlying message.
A belief need not be true for it to serve us. Therefore, the more important question to ask of an epic is whether it serves us, rather than if it is true.
