Few things in the development of film have been as ridiculous and childish as 3D. A gimmick to begin with, the past year or two saw an upsurge of voices claiming 3D would soon become the norm for film as a medium of art, especially after James Cameron's Avatar (a terrible film in any dimension) did rather well at the Box Office. Thanks be to the movie gods, it now seems that most sensible people have realized that there is no qualitative difference between the current 3D technology and that of 50's House of Wax fame, a childish distraction that has nothing to do with good cinematography, storytelling or conveying what is beautiful.
Roger Ebert, a longtime foe of the trend towards 3D, recently received a letter on his blog from Academy Award winning editor and sound designer Walter Murch. The letter is definitely worth a read and is a sensible summary of why 3D doesn't work either aesthetically or even biologically.
Here's hoping that 3D will soon be sent to the churchyard of bad ideas along with smell-o-vision.
