Well its a lightsaber it has to be crisp. Dont look the OT ones that was reflected material on camera that was looked like neon lights.. It has to look different from what a light looks like in real life.Because its not a lightt...right?
AOTC had the similar approach to the sabers but still the continuity was a big mess.
TMP made it more OT like but still with no blu ray release it doenst worth the effort...
