The book is so good - let's change it completely and create a move!

Rating: 6/10 (1 April 2018)

I can't understand how and most important question why Ernest Cline created such a script that destroys so many cool things about his original book.
I can understand why War Games has been replaced by Shining - this is just more popular movie reference that more viewers will understand. But why to change everything that made this book so good?
Many cool concepts from the book buried under tons of action scenes. Instead of slow character development we get into the action scenes right away.
We see real faces of all the main characters almost in the middle of the movie, which absolutely ruins climax of the first real life meeting that happens only in the end of the book. Well, you say - they needed to alter the book to have screen time for the actress that plays real-life Artemis. They could fix it very easily by showing real actress in the OASIS instead of that CG generated character. BTW, in the book - Artemis in OASIS looked very similar to herself in real life (just a little bit different). So they could easily give the screen time to the actress while staying true to the book. This is just a very bad excuse.
They removed references to many Atari games vividly present in the book. In the movie they only showed adventure. This is a movie about nostalgic references. Yes, I understand, Hollywood bosses decided that viewers don't remember Atari games from 80's.
In general all those changes made the key climatic scenes in the book so flat and so anti-climatic in the movie.
