they didnt continue the story the way sequels go.
1- the issue here was how this person randomly knows how to use the force without any training. People thought that the easiest way to explain this was parents but it turns out that this wasnt the answer.- Rey found out who her parents were. The answer fit with how they continued her character development and contrasts nicely with Ben Solo's arc. You just didn't like the answer, which isn't really the movie's fault.
- Snoke had precisely as much backstory as Emperor Palpatine did in the original trilogy and what happened in this movie developed and advanced Kylo Ren's story, elevating his position as a villain. It's also basically answering the question "What if Luke & Vader had done what Palpatine suggested in Return of the Jedi?"
- We literally saw the government of the Republic blown to smithereens in the last movie. This one continued on with what happened now that the First Order is the only major power in the galaxy.
2- Again, this is a sequel. A sequel continues a story and it should tell us what the story is. They didnt, they just drop stuff there because it's needs to be there. It's not even writing it just bullet points happening.
3- Yes we did. And that caused zero reaction from the republic? How are the FO a major power? How are there no fleets from all member planets being launched to destroy this enemy that they should not have ignored?
no, ths criticisms are more in the order that they dont have any overall arcs, it's just bullet points being throw out that dont really connect.These criticisms seem more on the order of being upset that Quicksilver isn't resurrected, reality isn't rewritten to bring in the X-Men into the MCU, the Red Skull doesn't pop out of a Tesseract portal, and Thanos doesn't create a legion of past villains for the final - I.E, all the wild speculation and fan theories don't turn out to be true.
it looks like Disney really wanted to dump it all but they backed out and threw the OT people there out of fear and now we have this half sequel half new story that doesnt make sense.
