She had charisma out the wazoo. I admit to loving and rooting for B/G during Rodnina's latter years... they were the "home team" after all. But Irina was just so WOW.
I know it's an old complaint of mine, but I'm afraid we'll never see pairs programs like those delivered by the icons of the sport. The Protopopovs (and B/G for that matter) took their time. They presented the elements in the most beautiful and finished fashion. They weren't rushed from one trick to the other like CoP skaters are today.
