I will agree that the duels in the PT may be more visually stimulating and appealing, but in terms of characterization and emotion, the OT duels are way ahead of anything in the PT.
Without any character development or emotion, the flashy fights become boring and moot.
If I can skip everything but the last minute of the fight and not miss anything important to the story, then it is a failure as a scene.
This is a legitimate criticism. The lightsaber duels in the Original Trilogy definitely contributed more to the character arcs.
Admittedly, other than Qui-Gon’s dying wish that Obi-Wan train Anakin, Mace Windu’s duel with Palpatine, and the entire duel on Mustafar, most of the lightsaber duels in the prequel trilogy were less emotionally powerful than in the original trilogy even if they made more tactical sense.
