Humor my lack of technical lexicon here but,
The word that comes to mind with the prequels is "sterile". Big, bright empty environments that look like plastic. Conflicts with no emotional investment or stakes. Fights that have no internal story telling to them - there's the start of the fight, lots of fancy moves, and then after along while something happens to resolve the fight.
The fights in TFA are short but are jam packed with visual story telling in nearly every shot. There's an ebb and flow to them and we can tie those things directly to the characters.
Just look at that tracking shot: this from the tail end of the fight. Rey is exhausted and clearly outmatched. Kylo Ren is driving her backward with heavy blows from his saber, while still wielding it one handed. He's on full ego-stroking mode while trying to demonstrate to Rey that she has no chance. He's been instructed to bring Rey to Snoke and his goal is to pound her into submission. The disparity in confidence and ability between the two is enormous, and the way the tracking shot moves more slowly to the right than Rey puts emphasis on how she's being driven back.
The lighting is gorgeous, and the setting unique to the series. It uses the red/blue from the sabers to highlight the environment (and in the next moments the characters).
Perhaps my favorite shot in the entire series, for its composition, framing, how it distilled the central conflict in the film, the gorgeous use of color and location.
There no such thought process to the fights in TFA.
(I realize I'm participating in the re-litigation of TFA, but at least we're in different territory here, and discussing stylistic and story telling choices that will probably impact Ep IX in similar ways as they impacted TFA. Let's not dip back into Mary Sue territory.)
