WTF Happened?

Rating: 2/10 (10 July 2018)

Saw this yesterday and thought - WTF happened here?!? Came to IMDB to find out that as of today it had a 7.7* rating which is just ridiculous. I had to reset my password to this site, because I don't do reviews usually. But this made me go through the trouble.
I read the book. I thought it was mediocre, but you know Young Adults and all that. Listened to the audio book a year later when I found out about the movie coming out, and it kind of grew on me. Still very much a mediocre book, but I'm a huge fan of the 80s, games, geekdom and all that so I had an appreciation for it.
Then yesterday I saw the movie. The movie made the book look like the best literary master piece of the last 1000 years. This movie depicted EVERYTHING that's WRONG with Hollywood. The story was butchered so badly that at best it had like 20% of the book. Character arcs were changed, story line was nothing like the original, the essence of characters was completely butchered and changed, new characters were introduced that added absolutely zero to the movie. The romantic story was so Hollywood-ized it was barf worthy.
Here's the summation:
People who had read the book thought - "WTF happaned?"
People who had not read the book thought "WTF is happening" throughout the whole movie.
