As a person that read the book AFTER watching the movie adaptation, I was not that dissapointed with the film. The book was incredible and in my opinion far better than the movie, but this doesn´t means that the movie wasn´t good just not in the same way that the book. The film misses lots of details that were in the original READY PLAYER ONE and the main plot that even though I know it isn´t always possible to recreate the book, i think that Spielberg had a lot of resources that he did not use; whith and argument as ashtonishing as the book has with lot of juicy parts that he coud have included. I read the book because I thought that the movie was really great, when i finished after two days of intense reading i watched the movie again and i couldn´t see more connection with the book than the names of the characters and the main idea. Despite the fact that the movie has a lot to be jelaouse from the book, it is not a bad film is just that after you read the book you don´t see where the movie came from.
