I would give it a 6/10 at best, and that's pushing it. I'd probably settle with a 5/10.

+ Finally explain why there's the weakness in the Death Star that allowed the rebels to destroy it later, and that was done in a meaningful way

+ Visuals and set pieces were great

+ Vader scene at the end

- Sloppy editing, in the first half especially. It was jarring to keep jumping between so many planets at the start.

- Poor pacing. The first half dragged by and I was actually bored watching it.

- Lazy scenes and other things that don't make sense. Like when Krennic is talking Galen Erso at the very start, all the shots of Krennic have extremely strong winds blowing his white cape forward but all other shots of the scene showing either mild or no wind at all; stuff like that bugs me. Saw saying that Bodhi would lose his mind after dealing with the tentacle monster yet he seems perfectly fine after a brief bit of being out of it. The opening-and-closing contraption in the archive room had no apparent purpose other than to ramp up the drama. Cassian somehow not only surviving his fall in the archive room with no apparent injuries but also having the strength to climb all the way up and be fast enough to get past that contraption. Why the heck is Leia on that ship in the middle of the fight other than to provide a convenient connection to A New Hope (edit: apparently there was a line explaining why she was there, I must have missed it). etc etc etc

- Cheesy and weak dialogue. Probably one of the worst parts of the movie for me. It made it hard for the actors to do a good job with what they were given. Super cheesy, and it's inexcusable to make Darth Vader of all people to make a pun. "Be careful not to choke on your aspirations" is acceptable in an Arnold Schwarzenegger movie but on Darth Vader it's ridiculous.

- Bad acting. Some of the acting was downright atrocious (way too over-the-top Forrest Whitaker, the pilot Bodhi, and Krennick were some of the worst) and almost every person felt flat and bored saying their lines... however I think most of this can be attributed to bad directing

- Boring and flat characters. I felt nothing towards most characters. Krennick was as stereotypical of a villain as you can get (only interesting thing about him was that he was killed by his own creation). Jyn was cold and unrelateable (and felt like a poor rehash of the "female orphan with family issues who's actually a badass and ends up becoming the hero" that worked for Rey in The Force Awakens) which made it super hard to like her, and her introduction felt so rushed. We go from seeing Jyn as a young girl and then skip immediately to her being in jail for some reason and getting into the thick of things, so we have no time to appreciate her background like we did with Rey. One of the more interesting things about her is her relationship with Saw but we only hear about it in a short exposition and then he dies. I was not a fan of Felicity Jones. Bodhi was basically a worse version of Finn (defects from the bad guys to become a hero with the resistance/rebels, except it's never really clear why he defects other than that he had a conversation with Galen). K-2SO is only there for comic relief, felt way too human (moved and talked too much like a human) and I just knew how his story would end, it was all so predictable. The characters were also just stuck in teh same roles through the whole movie, and the main heroes felt like they were fulfilling some social justice quota: the main heroes were a female lead, hispanic sidekick, two asian guys, and an arab. I'm all for diversity in movies but that felt forced. The last thing I'll say (I could go on) is that they were so forgettable I only remembered Jyn's name after the movie; everyone else I had to look up.

- CGI people. I can understand why they wanted to simulate Tarkin and Leia with CGI and I can applaud their effort but I don't think the technology is quite there yet; both people felt so off and weird and it was disconcerting watching.

- Music was extremely forgetful and only had the Star Wars theme at the very end. This I can't fault Michael Giacchino for because he only had 4 weeks to do it and I'm a big fan of his other work.

- NO OPENING STAR WARS CRAWL.

- More...

I'm honestly shocked at all the people giving it really high ratings and saying it's amazing. My entire family went to see it together and we all had the same issues with it and nobody thought it was a great movie. Overall it just felt sloppy, unmotivated, and like failed to prove why it deserved to be made and wasn't just a fan servicey cash cow.
