Rented Ready Player One last Saturday.
Love the book (basically a giant nerd jerkoff fantasy, but since I'm a giant nerd jerkoff, and grew up in the '70s/'80s, it's right in my wheelhouse). I've read it once, and listened to the Wil-Wheaton-narrated audio twice.
I enjoyed the movie quite a lot, despite it being almost-but-not-quite-entirely-unlike the source material. I figured the screenwriters decided the quest tasks in the book were a little too niche-nerdy (Tomb of Horrors, Zork, that Black Tiger game I have no familiarity with, etc) and also for copyright reasons probably couldn't have Wade playing David Leightman in Wargames, so I understand some of the story changes.
Anyway, 7/10, would watch again.
