I don't know why all the complaint about stuff in the movie that "didn't have a result." It's much more like real life that way - "we tried this, and it failed! It was pointless! It was a wrong turn! It didn't turn out the way I expected!"
It's actually kind of refreshing from the "every single small moment in the story is successful and/or has an awesome purpose and/or we succeeded despite terrible odds." I mean, I thought it was actually nice that they failed to disable the tracking device - it was a million-to-one mission, and it actually failed!
Something I've just realized about this thread and most of the discussion on this movie though - it's lots of what people don't like - but very little of discussion what people were expecting. I feel like most of the disappointment and dislike is due to unmet expectations. But what expectations were there? Stuff like that...
Stories are not real life. They are not about being realistic or emulating reality. They're about exploring very certain aspects of humanity, and frankly, I would say the more "realistic" and down to earth it is, the worse a story it is. I hate, HATE, when people say this... there's a whole pseudo-genre of work for you, pal: Literary Fiction. Eat it up, thousands upon thousands of short stories and novels and unfinished works on boring, mundane real-life, slice-of-life bullshit. Who, in their right minds, wants to hear about the trials and tribulations of the average? How lame. How presumptuous to assume that any given person wants to hear about a life they are already living as if it is something they have yet to grasp the beauty in. Boo to you sir, I say Boo.
A story is a story, and how dare you defend both failure and a lack of imagination. Realism is overrated. Of course, this movie isn't realistic at all, but if you want to say that story is much more like real life than it has been before--well let me tell you it is one of the technically worst stories I've ever seen. The first two thirds of the movie are entirely invalidated by Finn and Rose's failures, and has to be MANUALLY reignited by the Codebreaker because Johnson clearly wrote himself into a corner--which he continually does, leading to my next point. Aggressive amounts of Deus Ex Machina. There is no truly overarching problem or villain. Rey has almost no interaction with the other characters, and SERENDIPITOUSLY saves them all at the end of the day. Luke changes his mind about helping out for almost no reason. Snoke is a macguffin. The entire scenario of running down the rebels simply because the FO can is ridiculous given the character Snoke and Kylo were set up to be. My god man, it's truly awful--and that is without considering it in the frame of being a sequel to TFA. Add incredible gaps in character personalities from TFA, an inability to show characters bonding emotionally, several story lines just fucking stopping or not developing, constant plot armor, and accompanying consistently bad decision making from most characters and you have... well, one incredibly shitty script.
And speaking of expectations, we were all expecting a Star Wars movie. This was not it. Everyone here is talking about expectations like they don't matter. They fucking do. It's so frustrating. Their are high expectations for Star Wars. Secret Missions. The Force. New and Wonderous Planets. Aliens. Blasters. Big Battles. Lightsaber Duels. AND a general sense of wonder and scale. This movie KNOWS it needs these things and tries and fails at making them tangible. And you know what? You can break, SMASH every single expectation you want, but the movie has to be GOOD for you to do it, and the writing alone was movie-ruining.
