The studios, looking for ways to make money, convert what seems like every other movie to 3D--most of the time in post-production--because they want more profits. They would rather put profits before character development or story.
I'm not going to pay a few bucks on top of regular price just to watch a movie in 3D for the same reasons as Roger Ebert lists.
3-D is a waste of a perfectly good dimension. Hollywood’s current crazy stampede toward it is suicidal. It adds nothing essential to the moviegoing experience. For some, it is an annoying distraction. For others, it creates nausea and headaches. It is driven largely to sell expensive projection equipment and add a $5 to $7.50 surcharge on already expensive movie tickets. Its image is noticeably darker than standard 2-D. It is unsuitable for grown-up films of any seriousness. It limits the freedom of directors to make films as they choose. For moviegoers in the PG-13 and R ranges, it only rarely provides an experience worth paying a premium for.Or other reasons such as:
6. THERE’S MONEY TO BE MADE IN SELLING NEW DIGITAL PROJECTORS. These projectors are not selling themselves. There was initial opposition from exhibitors to the huge cost of new equipment and infighting about whether studios would help share these expenses. Some studios, concerned with tarnishing the 3-D myth, have told exhibitors that if they don’t show a movie in 3-D, they can’t have it in 2-D. Although there’s room in most projection booths for both kinds of projectors, theaters are encouraged to remove analog projectors as soon as they can. Why so much haste to get rid of them? Are exhibitors being encouraged to burn their bridges by insecure digital manufacturers?Just read his article for the whole story.
7. THEATERS SLAP ON A SURCHARGE OF $5 TO $7.50 FOR 3-D. Yet when you see a 2-D film in a 3-D-ready theater, the 3-D projectors are also outfitted for 2-D films: it uses the same projector but doesn’t charge extra. See the Catch-22? Are surcharges here to stay, or will they be dropped after the projectors are paid off? What do you think? I think 3-D is a form of extortion for parents whose children are tutored by advertising and product placement to “want” 3-D. In my review of Clash of the Titans, I added a footnote: “Explain to your kids that the movie was not filmed in 3-D and is only being shown in 3-D in order to charge you an extra $5 a ticket. I saw it in 2-D, and let me tell you, it looked terrific.” And it did. The “3-D” was hastily added in postproduction to ride on the coattails of Avatar. The fake-3-D Titans even got bad reviews from 3-D cheerleaders. Jeffrey Katzenberg, whose DreamWorks has moved wholeheartedly into 3-D, called it “cheeseball,” adding: “You just snookered the movie audience.” He told Variety he was afraid quickie, fake-3-D conversions would kill the goose that was being counted on for golden eggs.
Was there any reason that Gulliver's Travels needed to be released in 3D? It wasn't going to be a blockbuster at all. It didn't add any thing to the story.
