Not at all surprising - with only rare exceptions (The Polar Express, Avatar, Hugo, and Immortals are a few), Ebert has inveighed against 3D, and here he is taking on Big Jim re: Titanic: Now for the final flaw. It is, of course, the 3D process. Cameron has justly been praised for being one of the few directors to use 3D usefully, in "Avatar." But "Titanic" was not shot for 3D, and just as you cannot gild a pig, you cannot make 2D into 3D. What you can do, and he tries to do it well, is find certain scenes that you can present as having planes of focus in foreground, middle and distance. So what? Did you miss any dimensions the first time you saw "Titanic?" No matter how long Cameron took to do it, no matter how much he spent, this is retrofitted 2D. Case closed. But not quite. There's more to it than that. 3D causes a noticeable loss in the brightness coming from the screen. Some say as much as 20 percent. If you saw an ordinary film dimmed that much, you might complain to the management. Here you're supposed to be grateful you had the opportunity to pay a surcharge for this defacement. If you're alert to it, you'll notice that many shots and sequences in this version are not in 3D at all, but remain in 2D. If you take off your glasses, they'll pop off the screen with dramatically improved brightness. I know why the film is in 3D. It's to justify the extra charge. That's a shabby way to treat a masterpiece. Again, not a surprising verdict, but a shame nonetheless. If even Big Jim can't make retrofitted 3D work, maybe the case really is, as Ebert says, closed.
