Movies that you believe have an unfair reputation

Um, I think you're looking into the 'drinking green breast milk' part of my comment a bit too far there, it was just describing Luke's new kind of lifestyle as a recluse at the start of The Last Jedi, nothing more really. 

Nobody missed the entire final act of the film, that Luke wasn't like that from the start of the picture is what's disappointing. He had a great arc in the original trilogy and to discover that he became a broken clock of a person in recent memory just feels like a knife to the heart for many fans, it wasn't a good subversion of expectations it felt like a middle finger - and it's kinda telling when you have interviews and Twitter comments from Mark Hamill strongly suggesting he didn't like what Johnson and Kennedy were doing with the character. Luke at the end of season 2 of The Mandalorian, now THAT is the Luke Skywalker everybody wanted. 

Subversion has become problematic in recent memory because most filmmakers applying it to genre entertainment do not know how to effectively do it. Psycho is an example of subversion done right, you get to know who Marion Crane is and feel all the emotions she has when she decides to take a huge risk in her life and when she dies nearly halfway into the picture it is an absolute shock because you are set on following her arc from start to finish. We only saw a little bit of Snoke in The Force Awakens, there was anticipation to learn more about him and what he is to Empire and The Last Jedi right before they almost did anything with him killed him off. It's not clever or interesting, it's pretty sloppy storytelling especially coming off of The Force Awakens. Johnson's whole approach to The Last Jedi was essentially not to make a second half of a three part story but a second half and a third half of one. He threw out most of what Abrams was trying to set into motion and made it so hectic for Trevorrow that the latter eventually left and Abrams was brought in to try and fix the mess Johnson had made. In all honesty, The Last Jedi serves as a good example as to why you don't let somebody like Rian Johnson try to take over the driver's seat in the middle of a trip, Star Wars is not a kind of property you can deconstruct as much as you like and expect everyone to love it in the end you have to follow certain rules and respect certain things in the canon as well as what past artists have contributed. If anything he should have been rewarded with a one-off that was a stand alone story set in the Star Wars universe, but nothing major to where it would be impactful on the property as a whole. 

They gave her no origin, said her parents were nobodies, and offered no real explanation for her amazing force abilities, she was OP from start to finish and just learned to home in on certain powers here and there, not a lot of growth. 

I would say because she didn't she use it at all in The Force Awakens is what brought on such raised eyebrows, if she had done something of similar note in that film there probably wouldn't have been as much complaining about that particular moment. 

No, fans wanted a Luke Skywalker who was a wise old man who despite the many challenges he had faced and was standing in front of remains loyal to his purpose and friends, and if he had to go at least go out in a blaze of glory that reminds everyone how well he lives up to his legend. They didn't want a Luke Skywalker who was a quitter who didn't anything more to do with the Jedi or the force or even his friends and family, who tried to terminate his own nephew while they were resting, turn his back on Rey for real, and kick the bucket after projecting himself like Loki. 

In that case, why bother having Snoke at all then? Abrams was clearly setting them up for something big with The Force Awakens, and Johnson killed him off in what is supposed to be the very middle section of a three part saga. It would've been different if he was not built up as such a huge powerful being and just a random guy barking orders, but clearly Abrams and Johnson didn't see eye to eye there, and we can all blame that on Kennedy for not being a good manager. 

JJ Abrams had mapped out a trilogy with other writers with the intention of co-writing and directing The Force Awakens but laying out certain plot beats and arcs that the coming writers and directors had to follow but work around to still give their own kind of flavor to it. Johnson pretty much took what was laid out and threw most if not everything in the trash and decided to tell a story that acted not just as a sequel but even a finale of sorts, this wouldn't had happened if Kathleen Kennedy had a better grasp of storytelling and what is better for the property but instead she took much of a liking to Johnson's personality and didn't stand in their way. The result? A film that strongly divided consumers, made longtime fans of the property more questionable of Disney's handling of the franchise, and pretty much stomped out whatever plans Kennedy had going forward. Now with the success of The Mandalorian, most of the franchise's future is on Disney+ and Kennedy is only really overseeing two or three upcoming Star Wars productions as extensively as she used to, all others will be looking more towards Jon Favreau and Dave Filoni for guidance. Actually, Trevorrow tried his best to work around The Last Jedi, many have called his script titled Duel of the Fates a very fine continuation that would've wrapped up the whole Skywalker saga good enough but Trevorrow didn't see eye to eye with Kennedy in the end. 

Because she was still pretty OP and felt written as more of a concept than as a character. 

It's just a pretty lame scene all around, Leia deserved a better scene to show off her force abilities and Carrie Fisher(RIP) deserved better written scenes.
