Star Wars universe does have lasers of all scales and power levels.
Yet literally no one uses them well on a personal scale.
The Jedi (and Sith for that matter) imbue it with a power of magical stone, and then…use it as a saber.
To balance this stupidity, stormtroopers, clones and droids all use slow, non-continuous energy blasters. With actual lasers, they could insta-kill any Jedi, but they cannot, because otherwise the movie wouldn’t exist.
You can’t stress that enough. I love sci-fi, but I never really fancied Star Wars.
Now, as a dad, I rewatch the movies and replay scenes with my son, and the similarity with fantasy action movies strikes me. For example, the beautiful display of alien species and habitats.
