It's true that you don't need 3D for story telling however 3D depth perception (not 2 D) is an important sensory experience. Try driving/walking with one eye!
Interesting thing is... Yes, it's an important part of sensory experiences but it already exists in movies without 3D effects.
Depth perception has been painted on flat canvas since the Renaissance artists came up with perspective. Paintings (photographs and moving pictures) have created depth perception ever since.
No, the 3D effect isn't required to see depth in film. That's why it's kind of a gimmick.
My spin here was just that 3D is
not (as some in the industry want you to think) as inevitable as color in film.
Color is required to see the
real color of Lauren Bacall's dress, or the shades of a sunset. B&W films where these things come up in dialogue isn't pertinent to the audience due to limitations of the technology. That's why, as compelling an experience as a black and white film can be, color was an inevitable improvement.

I see what you're saying. But you're talking about different forms of media - which I believe the 3D movie
really is. 3D movies are a bit like watching a sporting event, WWE or a live play or concert at the movies instead of someplace those activities usually take place. It's not a movie - it's a different experience.
That's why it's difficult for film critics like Roger Ebert to review them as films. He has to take them on their merit as a movie only. He's only slightly more qualified to review Friday the 13th 3D as he is a Star Wars video game.
I'm not saying these other mediums are a waste of time.
But when you start putting on a helmet and experiencing holographic "stories" as if you were in the middle with full sensory input - it's not a movie.
Who knows... one day in the future people may look back on 2D movies like today look back on those little booths from 1920s Penny Arcades where you turned a handle to advance the frames of a short, silent video such as a hula girl or Babe Ruth hitting a homer.
Those weren't movies either.
