Do you know that all the powers/abilities that was shown in the movie is rooted in prior material.
in the old EU YES
but not so in the Disney Cannon/Legends paradigm.
plus even in EU teleportation was very rare, always people not specifically objects, and usaully after much training.
healing similar thing.
so far it hadn't been in the Disney Cannon or even pre-disney movie Cannon, was very rare, allways people, and usaully after much training.
as for force ghosts interacting with physical objects that was never a thing atleast not that ive ever seen in the dozens of EU material i consumed and the pre-Disney Cannonical answer comes from the The Complete Star Wars Encyclopedia
force ghosts can "interact with the living, albeit not physically".
In the real world: 1903, first flight, 1945 the first atomic bomb dropped.
Another example, 1944 the V2 rocket shows up, 1969, Man lands on the moon. You say that 40 years is too short for innovation yet in the real world we had some pretty sizable leaps.
a machine the size of a small moon with substantial power requirements that took decade(s) (time line implies about 19) to build to down to the size of a large cannon that can be mass produced by the thousands.
this is a leap in innovation we still havent achieved even with our great leaps the last few centuries.
This is forgetting that the death Star II didn't even get fully completed, the only reason they didn't build multiple death stars at a time was according to expanded universe sources because the Empire couldn't afford the credits to do so, in fact in order to even complete the first one the worlds involved were under hard austerity measures.
that not only practically bankrupted the Empire but decimated the few planets involved in the actual construction.
but they could at least scrounge up the credits materials and workers to do the project, somehow now a less affluent first order ( or technically the Emperor himself outside of the first-order because while he controlled snoke as puppet he was supposedly dead thus wouldn't have complete control this time without obfuscation) without any proof of help, finances materials etc. was able to make thousands of equivalently powerful planet destroying cannons, no mention of how the Star destroyers got the power the fire said lasers as well.
nice try but this argument of yours doesn't hold water.
Overall, I don't walk into a movie and start disputing it because that's not what the real world acts like. Its a bit of fantasy and storytelling and if you're too critical, then you lose the bit of magic and enjoyment.
that's my problem, I'm not walking in arguing it's not like the real world, I'm walking in arguing is not like the Star Wars universe and helps ruin the universe.
I'm trying not to lose the bit of magic and enjoyment because like I mentioned before it is a turn your brain off fun movie and it did everything it could correct the mistakes in the last Jedi, because it was painted into a corner it seemed like it was probably the best movie it could be for what it is/where this trilogy was left.
if I take the lore out of the equation and just turn off my brain, I can say I enjoyed watching the film but that's where the like ends.
it's because of that I'm not nitpicking it over continuity errors like how kylo loses his pistol one scene to another for no reason.
zorii gets off world without the captains medalion mcguffin after specifically mentioned it was her only way off.
not to mention her attitude switch for no reason or other rather self-contained errors such as not knowing direction up, the fact the ships were raised able to raise out of the ground and it didn't destroy the ships transponder, lack of usable shields in atmosphere the fact every ship didn't have said transponder, the fact Rey can force lift all those boulders and yet tries to use her arms to lift the tree off BB8.
there are literally dozens upon dozens of little nits I could pick but those won't affect the future so I could care less every movie has some.
as a hardcore Star Wars fan its the lore abuse that is offensive to me, I didn't spend thousands of dollars on Star Wars Merch over the years, hundreds of hours in the games both playing and helping in some of the modding scenes to have such a beloved franchise destroyed by people that just want to turn your brain off popcorn flick once
not understanding the repercussions to the universe as a whole, because the casual audience won't care because once their movie/trilogy is done they check out until hype tells them otherwise.
but to the hard-core fans who pay attention to everything Star Wars we are left picking up the pieces, lots of the stuff in this movie aren't self-contained to the skywalker's, palpatine's etc. and will have a ripple effect throughout any new content.
similar to how drugs might feel good in the short term but have long-term negative effects this was Disney's hardcore drug binge.
