"Quality" is defined by the consumer, no one else.

Is "quality" the same old porn star in his 50th title, with extra make up, costuming, and exotic location, or is "quality" a new dick getting sucked or a new ass getting topped?

The consumer gets tired of the same actors, the same director, shooting the same repetitive scenes...

A couple of years ago, after editing about 100 projects for a company, I suggested that they buy a new couch that was featured in half or more of the projects. That's a big reason why I like to travel and shoot on location.

The consumer is looking for "variety", in specific niches. Whether a DVD is produced with effects, special lighting, make up, costuming, exotic locales, the consumer is looking first for "niches" that he can identify with.
