can someone explain what exactly makes so many people hate TFA and/or TLJ?
For me personally,
TFA:
Finn - He starts off like an interesting character. A stormtrooper who had PTSD at seeing all the violence caused both by his people and losing people close to him. You think they are going to take his character into some pretty dark places and expand on this right? Wrong.
Once he "escapes" they throw that entire part of his character away and basically ignore it, doing a terrible disservice to what actual PTSD does.
Not only does he seem completely unfazed after his escape, but hours later he's literally LAUGHING while watching people that he likely grew up with and knew are getting killed by Rey/Han/Chewie. It just felt really really stupid. They could really have done something with this, making him averse to violence, and making him NOT want to see his friends die on either side, but instead they basically just ignore his entire setup and make him the "funny man" of the movie, while not really giving him much else to do aside from that.
Rey - I didn't like how she always seemed to know and was able to do everything she needed to out of the gate without fail or having to learn. It would have been a better character arc for her if she had a chance to grow throughout the film and then the second one to learn more about the force and how to use them. Instead she somehow is able to instantly use the force whenever she needs to. She is able to repel a jedi-mind trick and even turn it back onto Kylo. She can force pull/push things on top of that too. Then she was able to pilot the falcon without ever being on it (this was explained not in the movie but a book, that she had played "sims" and thus knew how to fly). All of these types of things I just felt like it was a chance for them to show her character grow over the course of the movie but instead they just magically let her do them without ever letting the audience see her learning/training to do them and thus giving her character arc more growth which I think would have helped.
TLJ:
Rey - Rey is actually pretty good in this movie for the most part I felt it was a step up.
Finn - Well Finn is in the movie and instead of Rey he basically gets Rose who just attaches herself to him without him ever getting to really know her. It felt so forced to me. He had a big moment near the end and that was about it, felt so underused.
Rose - Mainly it, again like Finn from TFA, felt like two separate writers wrote her character in the beginning and then another person wrote her character at the end without even knowing what her story was up to that point.
The movie starts off and Rose is literally stopping deserters from leaving because she doesn't want her sisters sacrifice to be in vain. She cares enough about the cause to do this.
Then she runs into Finn, and basically instantly falls in love with him (without really feeling like he feels the same for her). Then at the end when he's about to make the ultimate sacrifice to save Rey/Leia and all the people she....stops him. She literally went from stopping deserters to actually throwing EVERYONE under the bus in order to save Finn, a guy she literally just met a few hours ago. For all she knew it could have worked, and afterwards if Luke hadn't shown up she would have literally gotten everyone else killed all to save Finn (who likely would have both been killed along with her if Luke hadn't shown up).
Kylo - The moment he hesitates to attack Leia's ship, his talk about putting the past away. That moment when they tease Kylo + Rey, I wanted that to happen. Something that just subverts the expected Kylo = Villain, Rey = Hero to stop him, but they basically take both him and Rey back to the same place they are in the beginning of the movie in terms of the characters motivations and arcs, with Kylo just being the big baddie now (someone Rey has already beaten, which makes it not seem nearly as threatening as Snoke.
Poe - Talk about a clusterfuck. He cost them so much at the start of the movie, and then Leia gives him a slap on the wrist and then Holdo doesn't let him in on their plan, which in turn made no sense and felt like just bad writing to force conflict that would have been solved simply by her telling him the plan instead of constantly bickering with each other.
Then there was Rey's lineage and Snoke, both huge disappointments that are basically throwaways, she didn't have to be Luke's, but it'd have been nice if her parents were someone from the past movies or something, just that "tease" from the first movie and then it basically shits all over it with "her parents are nothing special."
Overall the movies just remind me of Jurassic World. On the surface they are slick and polished and have some nice idea's here and there, but they are just missing something.
