I saw this last night on a Netflix disc on recommendation from my daughter. We were discussing the Showtime series "Billions", and how there is so much pop culture injected into the show. It really makes it fun to watch when they keep bringing things up from the past that you really lived through and embraced many years ago. She then urged me to watch this movie.
"Ready Player One" is a gamer's movie, and is entirely geared to a younger audience... but Spielberg has loaded this film with tons of pop culture, mostly from the 70's and 80's. Much of this would go way over the heads of their target audience, because the material came way before they were born. It's a lot of fun to catch everything they do. The entire scene with "The Shining" is amazing. Had to post this.
