Thing about the PT is that the entire idea of the Jedi and the force was completely changed. We would assume that Jedi were calm and do a fair amount of sneaking, never ever rushing into battle, only fighting when neccesary, and when that usually happens, with blasters. Lightsabers are for civilized duels between mortal enemies, not for just fighting with whenever you get the impulse. The Jedi in the OT were even designed to be like Samurai, Knights or Ninjas, not intergalatic fight-crazy warriors. The lightsaber fights in the OT were fahioned after old Knights or Samurai fights.

In ROTS, George just gave everyone a lightsaber and said, "Have at it." That was basically the whole script. Nothing like the REAL Jedi in the OT.
