Eh, if he follows true to form with things VIII will be the darkest one with IX bringing a mix of light and dark. It's a pretty standard formula for planned trilogies in general, moreso with Star Wars where they seem to be deliberately harkening back to the original trilogy.
"It's like poetry..."?
Better yet, the armor apparently actually makes blaster injuries worse. Get shot in the center of the chest wearing stormtrooper armor? Dead instantly. Get shot in the shoulder wearing a poncho? The cloth isn't even burned away completely.
I think there's something about blaster fire that makes it have a concentrated center? A shoulder wound is not on the same general degree to a chest wound in terms of survivability. (unless major blood vessels are hit, but I've no idea how blaster weapons work)
Maybe that means Leia was hit by a glancing shot?
Contrary to popular belief, getting shot in the shoulder (at least with projectile weapons) isn't a joke. If it hits the subclavian or brachial artery, that's really heavy blood loss followed by death if not stopped (though the blaster bolts probably cauterize). If it's closer to the collarbone, that could mean a collapsed lung. If it hits the joint, that's a ruined limb. Moreover, although blaster bolts seem more likely to cause deep tissue damage than shattered bones or severed blood vessels, that still could mean a crippled limb, especially given that they're apparently powerful enough to burn straight through armor (both stormtrooper personal armor and a Jawa sandcrawler, for example), I'd rather doubt that it's a superficial injury to be recovered from over a few hours. That's not a through-and-through with a bullet, it's a blob of plasma losing containment against your skin.
Getting shot with a slugthrower is basically a matter of luck: if the projectile doesn't hit any vital blood vessels (or vital organs, both because of their own functions and because of their tendency to be full of blood vessels), you'll survive, barring untreated infection from scraps of clothing or dirt forced into the wound. If it doesn't hit any joints, you'll probably heal with at most a little stiffness. Getting shot with a blaster weapon means, again, deep tissue damage
regardless of where you're hit. Severe burns, probably necrosis because a bunch of that is just gonna be ash and char. Probably part of why bacta was so important: it makes it possible to regrow big chunks of missing flesh. If you get hit by a powerful enough weapon in the torso or head, you're probably dead instantly. A limb shot wouldn't kill you--little or no blood loss--but you'd probably lose the use of that limb, either permanently or barring a lengthy hospital stay.
I mean, that's conjecture, but the dangers though different and hypothetical should still be real. Those Ewoks were getting one-tapped just like Stormtroopers and Rebel mooks. It was pure plot armor in the same vein as a contemporary-Earth protagonist getting shot in the upper arm but never actually dying or having the limb crippled. I recall it being something like a 20% chance that a shoulder shot with any sort of firearm is essentially death inside of a couple minutes, barring immediate medical treatment.
