When blowing up a 35MM negative to 70MM, it is true that one gets no 
improvement in the resolution of the original image (something from 
nothing?), but the image is sharper and clearer and suffers less geometric
distortion because you are not using the anamorphic lenses that 35MM
Panavision uses, for instance, to make a wide screen image.  These lenses
"unsqueeze" the image from the film to fill out the screen in a 2.35:1
aspect ratio.  Flat 70MM projection will give you a 2.21:1 aspect ratio
and a brighter image to boot.  The six-track Magnetic Dolby Stereo sound quality
is much better than the 4-track 35MM Dolby Stereo optical soundtrack, as
well.  More extended low and high frequency response, larger dynamic range,
and superior signal to noise ratios are some of the benefits.  

The result of a 70MM release print, which costs about 6-7 times as much
to make as a 35MM print, is greater impact of the movie-going experience.
I challenge anyone to view a properly presented film in 70MM and then
in 35MM and to state their preference.
