The Sequels got their name because they follow the Original Trilogy (OT). The Sequels were made by J. J. Abrams because George Lucas had sold Star Wars to Disney before they were made. When they came out most people hated them but I believe it's because they were supposed to follow what was laid for them (the Prequels and OT) but they didn't and made their own stuff.
If the Sequels were there own thing or were the first movies or something then these wouldn't be issues (except for the first which is unrealistic in any universe no matter how far away) because the Sequels would be the base for the rest of the movies to follow including lore, that would explain Leia floating, and how weapons work, which would explain the more sword like lightsabers.
