The film is set in 2045, with the world on the brink of chaos and collapse. But the people have found salvation in the OASIS, an expansive virtual reality universe created by the brilliant and eccentric James Halliday (Mark Rylance). When Halliday dies, he leaves his immense fortune to the first person to find a digital Easter egg he has hidden somewhere in the OASIS, sparking a contest that grips the entire world. When an unlikely young hero named Wade Watts (Tye Sheridan) decides to join the contest, he is hurled into a breakneck, reality-bending treasure hunt through a fantastical universe of mystery, discovery and danger.
Ready Player One is more like a seven-course banquet made up entirely of Pixie Stix and Pop Rocks-you certainly get a rush from it for a little while but once the initial effect, there is not much of anything else going for it but overindulgence.
Many of the book's references to Spielberg's cultural artifacts have been stripped away, but he imbibes the movie with flashes of colour and heart that rekindle a sense of wonderment that will transport many viewers back to their childhoods.
I'm sure that some will be more receptive to the avalanche of nostalgia than others... but I don't think one can deny the [film's] comment on the place of popular culture in our lives... [Full review in Spanish]
