I hate it that Star Destroyers can land on the planet and hover above its ground
I really hate it, and this started already during the Prequels, that those gargantuan ships can normally land on planets, move around and hover above ground just as easily as an X-wing or a speeder. Wouldn't it be nice to impose some limitations from time to time? Imagine the plot twist this limitation would entail. Imagine if you could only reach these ships with shuttles and leave them in dropships, and they could only be assembled and docked in a planet's orbit in a huge space hangar.
I believe that ever since the Prequels, they only look for things that "look cool." So, they liked the idea of Star Destroyers hovering above that citadelle and loading/unloading cargo, but it just makes the Star Wars tech too omnipotent, by having such huge ships defy gravity so easily.
People who will reply to this by saying that it's a space wizard movie, should try to read something from time to time. No matter how fantastic a story is, it must be consistent and it should from time to time impose some limitations on what you can do and cannot do in the story world.
