I read the book and was excited to watch the movie because of how much I loved Ernest Cline's novel. If you're looking for a movie faithful to the book, this is not what you're looking for. I was deeply disappointed after the first 10 minutes and kept feeling more and more heartbroken at the inaccuracies as the movie went along. I love Spielberg and I'm sure to someone who has never read the book the movie is great, but I just couldn't look past how different it was from the book and it ruined the movie for me.
