I understand. Yeah, the cinematography was not quite good. However I liked how agressive it was.
I really like ALL the styles of lightsaber duels in the entire franchise.
I love the fancy, elegant duels of the prequels because it show a more stylized use of the lightsaber proper of people who are highly trained in them, barely making any false or erroneous movements and most of the time keeping their cool.
I love the more crude and slow duels of the OT because it fits with the untrained, emotional Luke going against Vader, and Vader's own robotic body not being as agile. I loved the agression, the doubt, the "I'll just try to hit you as hard as I can".
I love the duel in Episode VII. It fits the characters perfectly. Kylo's movements are brutal. Most of the time he swings around his saber the hardest he possibly can. He is in to inflict the most pain instead of just cutting like in the prequels.
There are only two lightsaber duels I don't like in the entire franchise: Old Obi VS Vader, and Anakin VS Dooku in Episode II. All the rest I absolutely ADORE.
I'm actually very happy with how the duel in Episode VII turned out. It surpassed my expectations. I was too afraid they would try to imitate the OT style too much, but it has it's own identity. Not too slow. Not too fancy. A very nice middle ground with agression, desperation and cruelty.
