Did they need to put the stones back?

I haven't seen the movie, but I've seen all the 'Pitch Meetings', 'Honest Trailers', 'Everything Wrong With', 'How It Should Have Ended' (dubs, too) and so on, so I think I can sort of 'gleam' what was going on.

I just want to use a disclaimer like that in case I am completely misunderstanding the movie - not having seen it, and all.

Did they really have to manually do all that work? There seems to be SO many ways to travel in time, do 'wishes' and all kinds of stuff like that, especially after they get the infinity stones and the gauntlet, it boggles the mind. Couldn't they use just ONE of those methods to simply either cancel the original 'snap', or couldn't they use the Gauntlet+Stones to somehow 'wish' or 'rearrange reality' (one of them, as far as I know, is supposed to be a 'reality' stone..), so that the stones are automatically placed back, or that the original snap never happens, or something?

I don't know, I would probably be a bad moviemaker, as I can't understand all these obvious solutions, or why they use the same tropes so much - for example, everyone always lands WAY TOO FAR from the place they are going to, big army battles NEVER use actual, effective formations, tactics, proper squadrons, utilize the landscape/high ground to their advantage (except in one duel in one movie, where it was completely inapplicable)..

..but they just SCREAM like madmen while RUNNING TOWARDS EACH OTHER and then have this super chaotic MELEE fight, even though they have so many RANGED options they could use while the opponent's crazy team is running towards yours. Has any moviemaker EVER understood how this kind of massive war battles were ACTUALLY conducted in history? I can pretty much guarantee this cavemanlike 'AARRHGGGGH' while two massive groups run to CLASH to each other has never happened after people discovered fire, for crying out loud. Heck, even cavemen were probably more organized and intellectual than THAT!

Why do they make movies this way? Why can't at least light saber duels be 'realistic' - I mean, realistic to how dangerous AND how weightless those things are, so dueling with them would look NOTHING like it looks in the movies, but also, if they want to go that 'let's just mimic swordfights and ignore what light sabers are and can do', why can't they at least do THAT correctly?

Shadiversity has really good videos about how to do 'realistic AND cool' swordfights, and he seems to be tortured by the 'cross bind' that happens all the time, so much so, that I am already tortured by it, too, now that I know all the things they COULD do instead of just PUSHING..

In some crappy TV show, someone stabs someone else with a light saber, so it goes through her body.

Now, plenty of people have made videos and statements about how that would DEFINITELY kill you, although the character easily survives such a stab. I don't really care about THAT as much as I care about..

..them being light sabers, not swords. You don't have to PULL a light saber off your opponent the same way you ABSOLUTELY have to pull a sword. Again, these moviemakers are treating light sabers AS IF they are simply metal swords, using the same tactics, same kind of swings (at least the kind a total newbie would use), having same kind of weight, pivot point and 'minuscule damage', plus they still telegraph and 'baseball bat swing' like crazy.

But ignoring what you are presenting SO COMPLETELY that you don't even realize no one would EVER PULL a light saber back like that! You don't HAVE to, it's not a metal sword that's STUCK to the body, it's a LIGHT SABER, you can just move it anywhere and you still have it in your hand just fine, you can slice the opponent to little pieces by tiny wrist movements, but the very least, you can just move your wrist slightly up to slice the upper part of the body, then the body will fall, and there you go. No need to pull anything back.

But there's more!

Instead of PULLING it back through the SAME EXACT PATH AND HOLE while the stabbed opponent politely stays in place so you CAN... how about just flicking your light saber OFF? You can't turn off a sword, but you CAN a light saber. It's like 'automatic retraction', if you don't want to slice your opponent some more - why would you stab someone with a light saber if you do NOT intend to kill them? So you might as well slice them to some direction to get your light saber 'off' that body' (though most likely, the body would just fall, and thus auto-slice itself via the light saber until the light saber is 'free' anyway).

Nothing about any of these movies makes any sense. It's very frustrating, as if there's some Universal Law prohibiting sense-making in movies. I still wonder why they can't just make at least ONE movie with all those billions, that makes sense. It doesn't even have to FULLY make sense, just 'enough'. But nope.. every movie has like 200 things about them that do not make sense.. sigh.

Oh well, at least that means I have something to do.
