    Steven Spielberg never fails to blow us away with his imagination.

    The US director's latest film Ready Player One, which was released in Chinese mainland cinemas on March 30, is a story set in the year 2045, when people escape their hopeless everyday lives by putting on a VR mask and entering a virtual (虚拟的) world named Oasis. This fantasy land is filled with characters and settings right out of classic films and videogames like The Shining and Overwatch. It's a feast both for the eyes and mind. And at the age of 71, Spielberg is still “at the top of his game”, wrote reporter Rafer Guzman on Newsday.

    Indeed, Spielberg has always been a gamer himself or rather a game changer. When his thriller Jaws came out in 1975, it struck a chord (引起共鸣) with audiences all over the world and kept people from going swimming for fear. The film was also the first example of what we now know as summer blockbusters.

    “Jaws invented that form of pleasurable entertainment, wrote Stephen Marche on Esquire. It also turned sharks, in the popular imagination, from fish into monsters.”

    And again, in his 1982 film E. T. the Extra-Terrestrial Spielberg challenged people's beliefs that aliens are something to be feared by telling a story about a loving friendship between a space creature and a little boy. “Spielberg redefined popular sci-fi”, wrote Marc Lee on The Telegraph. “Extra-terrestrials no longer had to be a threat to humanity: the universe, he was saying, is also full of awe and wonder.”

    Now comes Ready Player One. When Wade Watts, the film's teenage protagonist (主角), finally prevents Oasis from falling into the wrong hands, he's given ownership of the virtual world by its late designer James Halliday. But Watts makes a decision that he hopes will make people want to appreciate their real lives, instead of spending all their free time escaping reality in Oasis, which is a real-life message that Spielberg is trying to deliver to the audience.

6.In fact, no one knows for sure {#blank#}1{#/blank#} it was that made him give up this opportunity.
