Criterion was simply the only way to get many classic films, especially foreign or obscure ones. They also give it to you the way it's meant to be -- original aspect ratio, non-colorized, etc. But they also tend to use very good prints and restore the sound and picture if they've deteriorated. Not a problem with a Beastie Boys DVD most likely, but with the greatest movies ever made, it's really great to see them in as close to a pristine condition as any of us are likely to see them. Sometimes there are also things there that film buffs would like -- like interviews with old stars and directors, little add-ons that make the whole package more interesting.

But mostly, Criterion is a name built on the quality of the sound/image, and generally does what are considered "classic" films.
