I wonder if the net had existed back then, if there would have been lots of "wide-screen gives me a headache" and "how come no directors discuss the story telling aspects of technicolor, it's just a money making gimmick?" discussions.

The answer is yes, because commentators of the time actually did. Sound killed the movies, then colour, then widescreen, now it's 3D and high frame rate. Historically speaking when it comes to movies, groups of people have always resisted the introduction of a new element.
