Roger Ebert [1] and Gene Siskel [2] were my introduction to analysis and argumentation. Watching two adults getting into a argument and discussing something using some sort of rules-of-engagement fascinated me. That they viewed a piece from so many angles, criticism is a skill and an art. Opinion shouldn't occupy more than 10% of result. ;)
I didn't understand the depth of that personal and professional relationship until I saw an interview with Ebert, where he teared up at the loss of his friend Gene. [3]
What are some other professional duos?
