How is the whole Rose side plot not a massive pile of world building? I mean if you’re going to complain about a lack of world building and then ignore the giant info dump in the middle of the movie, well that’s on the viewer.
The execution was off, it kind of involved RL politics, the characters were uninteresting and it all felt mostly pointless along with the general theme of the movie and the execution (a chase in space, in Star Wars). It also lead to the end of the move with an untrained kid using move object.
The weapons dealing thing was kinda decent that was OK.
Look at the original, Lukes (the chosen ones kid) use of the force was very subtle. He sucked with the lightsaber vs the drone and at the end he used the force to switch off his targeting computer. He managed to use move object after being trained by Yoda, and in RoTJ he uses mind trick on Bib Fortuna.
Anakin was trained for 10 years between ANH and AoTC, we see Padawans being trained in the temple in the prequels. In the EU/Legends Lukes and Leia kids had to be trained, the new Sith had to be trained, Revan had to retrain as well in KoToR. Training is also a big thing in the cartoons. If you don''t have a teacher find/use a holocron like Ezra in Rebels (who also had a teacher).
So TLJ basically did a big 180 basically ignoring 6 movies before it and had Rey and some kid using force powers untrained. Untrained force users usually have only very basic things like premonitions, dreams etc or at best wing it when they lose their temper. Throw in the force is female T-shirts Kathleen and co was wearing and they basically ignored one of the biggest tropes of Star Wars and what lore Obi Wan established in the OT's (it surrounds etc). Wonder why people get upset now?
Combine this with a crappy job f explaining the First Order and basically ignoring the end of RotJ (the New Republic fell part in 30 year really). Oh and also using hyperspace to fly into the gravity well of planets and using a ship as a hyperspace weapon also makes little sense in universe (why not just fire hyperspace X-Wings with Droids at star destroyers or fling a corvette at the Death Star). Why not just hyperspace a ship into the port thing on Starkiller base. Maybe Holdo is a genius but Akbar and Thrawn didn't figure it out and they are generally portrayed as being a genius.
They're either contradicting the older stuff or using stupid ideas what basically makes everything they did in the other 6 movies pointless. Throw in points like Kylo being an ineffective villain (he has lost twice already) and Rey being overpowered ( if she beat Kylo again so what he has already lost twice). Compare Reys trajectory to any of the OT 3 main characters she heas been written to be unbeatable with no really explanation. Anakin was the chosen one and he still got cut up by Dooku and Obi Wan. Luke got beaten up buy a wampa and lost to Vader. Vader never really lost until the end of the 3rd movie and it was the climax of the OT.
Basically instead of training to be a powerful force user just be an orphan or by yourself. You'll be knocking out those force lightnings way easier, the dark side isn't quicker or easier just don't have any parents around. Luke one of the most powerful force users ever got shown up by some untrained kid 13 years younger than him. Gebnerally things should make sense in universe and not contradict everything with no real effort made at explanation.
