Some people want movies to represent reality as closely as possible. Others reckon that imaginary details and unusual plot twists cannot spoil the film. I personally believe that it is unnecessary to make the picture extremely realistic and true-to-life.
First of all, there are such movie genres which involve unnatural phenomena, like fantasies or horrors, for example. How can a man turn into a vampire fledgeling in our setting? How can a monstrous pig with three heads exist? I’m driving at the fact that some genres are just not suitable for our reality, otherwise, without the director’s vivid fantasy, they would not even occur.
Talking about more or less realistic movies, like war films, documentaries, or autobiographies, I still presume that they should not be fully realistic. People go to the movies to abstract from their routine, to forget it for some hours, then why can’t a soldier jump three meters high, or the lonesome and dramatic writer write a letter to their first love in blood? Talking about documentaries, there are still some fake details in them. It is impossible to shoot :) a bird for 24 hours, so filmmakers sometimes film the animals of the same species from zoos or farms, telling that they are wild.
All in all, I believe that movies do not have to be fully realistic to satisfy their audience.
