The combatants were fast paced but every swing had intent. High degree of efficiency in a lot of their moves, counters were quick, and a minimum of useless swings. In general with combat, mastering a weapon means learning the efficiencies and learning to expend less energy while increasing damaging output. The next two movies went overboard with the cheese – extra flashy spinning of the sabers and twirling, more like cheer leading than combat (tho emo Anakin in RotS might look good in a skirt / uniform). And Yoda as the hyperactive chipmunk when he dueled, stupid.
