But I can imagine some people wondering: "3D, but what for?". Those are either colorblind or have a very poor eyesight, such as an old friend of mine who couldn't see any difference in the images with and without special glasses. Because others, particularly young people, clearly see the difference and let you hear a lot of "Wow!", "This is great!", "It's a killer!", "It rocks!" … to use a vocabulary which I have had to get used. The fact is that even the Queen of England was convinced.
By the way, have you heard of the last trailer of "Star Wars"? By the launching of the last episode (2015) Hollywood began to advertise about the newest version of the saga, and gathered a few thousands of aficionados to present them excerpts from the upcoming item. And, that one would be realized in what format?, should I ask you. Imax 3D. And, why Imax 3D? Because that's what young people presently want to see while attending a movie show. It just happens that the core target of action cinema is roughly the same as for video games: mostly (male) teenagers, with an average age around 20 years. Some years ago that population had deserted theaters and cinemas consecutively on a global explosion of the phenomenon of video games, to the point that to get by, Hollywood had no alternative but to begin to ape the (video) games in its own films, making in the beginning a lot of remakes of games (see Tomb Raider, which launched the career of Angelina Jolie).
But then Lukas, Spielberg and others (Cameron) didn't give up the fight, appealing to graphic designers, special effects experts, overseeing the invention of new materials which led for instance to 3D polarization ... And so on, until we got works as Avatar, Pi's Odyssey, Gravity ..., all in 3D as it is going to be the case of the coming version of Star Wars.
Do you understand now why 3D is that important? Because that is the way they found in Hollywood to attract the young audience back to the movies, and the most effective weapon to counter video games.
And, if you're not yet convinced, why not ask young people of your neighbourhood, while inviting them to visit this site ... And don't forget the little red-blue glasses!
