Thanks for the article. But really, the beef I had with your post is that you basically said (maybe not really meant it, but I ain't Professor X) that this 3D technology was "redundant" for the reasons stated.
And really, Nolan's quote there is a flat-out strawman. No one ever said that normal films in "2D" were, for all intents and purposes, "flat". Everyone gets the natural illusion of 3D. Most know about a few camera tricks like zoom and distance combos, depth of field / focus (if I remember correctly, in the Matrix movies they shot the Real and the Matrix scenes differently so that in the Real, there was a bigger contrast of focus between characters and background), lighting, camera movements, and blah blah blah.
We all know the difference between 3D animation and 2D cartoons. Everyone knows that live-action movies always deal with depth and 3D space.
So getting offended at 2D movies being called "flat" is as illogical and snobby as finding the need to mention that, in the so-called "black and white movies", there are actually shades off grey (and cinematography and lighting play a great role in that)!
When at the end of the day, a movie that is shown in 2D on a flat screen, without any ACTUAL 3D illusion based on feeding different signals to the eyes, is, well, FLAT, and providing this illusion DOES make a difference which you CAN tell from cinematography tricks.
This is basically all a giant case of pure hairsplitting. Sure, the glasses look goofy - but do you care when you have them on? ;)
I dunno. Nolan's objections seem to be rather of technical and practical nature, but in general, when I hear opinions like "great movies have been made for decades in 2D and no one felt the need for fancy stupid illusion tricks! this is just the new cheap Hollywood gimmick, ohh where's culture coming to" (i.e. objection against 3D without any real reasons about its current quality of execution, side-effects ect.), I usually just laugh, because it reminds me too much of the typical "grumpy ol' man" who just feels the need to assert that some "old school" thing was definitely better than this new crap.
Oh, what are these guys doing with all the amplifiers and electronic instruments... this is all mediocre, now the old masters with their real, acoustic instruments, now that was the real deal!
Guess I'm just carrying too much baggage on my back, eh?
Basically, as already pointed out in this thread, different stuff has advantages and disadvantages. From what I've heard about 3D (incl. I thing Avatar) is that it can cause unpleasant side-effects in more sensitive viewers due to the eyes receiving different information in an unusual way, or something like that.
I think it was headaches and slight nausea in the lighter cases; could be that those prone to epileptic seizures weren't recommended to watch 3D, but I'm not sure right now. Don't quote me on this last paragraph :D
