When speaking with a friend about whether or not the Star Wars franchise is child-friendly, the idea came up that even though people get cut in half, it is still fairly safe for kids because there is no blood (well, almost...). These three questions seem to show that many weapons in this universe instantly cauterize wounds.
This got me wondering if the weapons were designed this way (either initially or later changed) to keep the movie ratings a little lower and possibly open the franchise to a wider audience. I am wondering if anyone out of universe has commented on whether this was by design or if it just worked out that way? GL quotes would be fantastic, but others involved in design/production of the films would be great as well.
