Requirements for a Fight to be considered GREAT?

There is no sound definition for a 'great' fight, because for every requirement I can find an exception to the rule.

 

Tito/DLH was a total dissappointment for those of us who watched. The whole boxing world was angry and would have laughed had we called it a great fight. Yet we watch it now over and over, one, for the controversy, two, because the war we anticipated ended up a chess match, three because both fighters revealed the others weaknesses that would bother them down the stretch of their careers and define their careers. In other words it ended up being a great fight by accident or despite everything we think of as a "great fight."
