One thing you should never do is see the movie and then read the book.
Sometimes one can be quite surprised by reading the book which inspired the filmmakers to film it. Here we go with the “Minority Report” by Philip Dick. I’d watched the movie long time before read the story. Having started to read the story I did expected that I knew everything that Dick wrote even before my eyes caught it.

Yeah! Сhief Anderton got the red ball.
Yeah! Сhief Anderton discovered that there can be a “minority report”.
Yeah! Сhief Anderton came to see if he had one.
What?!Сhief Anderton did have a minority report?! Did the Philip Dick write a story which is less complicated than the movie?
Oh? Please, No! Chief Anderton did fired a gun and the man dead!!!

So, this is an example when the story can be turned upside down.
