Parents need to know that Ready Player One is director Steven Spielberg's much-anticipated adaptation of Ernest Cline's near-future sci-fi adventure novel about an avid gamer (Tye Sheridan) who spends most of his time in the Oasis, a virtual reality universe/multi-user game. Expect both virtual (i.e., in the Oasis) and real-life violence, although the movie's real-world violence isn't quite as traumatic as the book's. The in-game action can get pretty intense (especially when seen in 3D) and includes over-the-top shoot-outs (with every kind of weapon imaginable), all-out attacks, large-scale battles, destructive car chases, giant monsters, and a frightening re-creation of a gory horror film that includes ax attacks, zombies, and more. Outside the Oasis, there are assassination attempts, an explosion that kills civilians and destroys homes, forced labor, a car chase, and gun threats. Characters also flirt, kiss, and touch each other suggestively, and there's quite a bit of swearing (mostly "s--t," though there's a memorable use of "f---ing"). Although fans of the book, gamers, and Gen Xers with '80s nostalgia are the most obvious audience, you don't need to have read the book to understand or appreciate the story (in fact, if you haven't read it, you're less likely to be distracted by the massive story changes made for the movie...) and its themes of teamwork, perseverance, and valuing real-life connections.
