What plot? Trade Federation. Trade Federation. Jar-Jar. Slave child. Midichlorians. Pod Race. Darth Maul. End. That was the plot of Phantom Menace.
Oh come on, you can play that game with anything. A peaceful world was blockaded then invaded by the corporate bad guys and their robots, the heroes had to find a solution. Not great but functional, much like the original's 'we need to stop them blowing up planets'.
Force Awakens by comparison spent its screen time ignoring the declared plot (find Skywalker) in favor of bumbling from one comedy action sequence to the next for two miserable hours. Look, to be clear I don't like the prequels (I enjoy them, but I don't think they're good) and I'd agree with all your points individually, probably, but I think the Force Awakens is terrible, and it doesn't work as a Star Wars film. The prequels, while (mostly) bad have functional plots, and are functionally Star Wars films, you can watch them and see they were largely made by the same people.
Actually this is a venting thread, let's do this properly.
The Force Awakens
I absolutely hate this film. Which is a shame because I like the cast, and the effects are mostly pretty and the new X-Wings are gorgeous.
Star Wars tells a simple story of a rebellion toppling an evil empire. Along the way, Luke Skywalker grows to become a master. Han Solo overcomes his selfish scoundreling, to become a heroic scoundrel, then a respected general. Han and Leia declare their love for each other. These are all elements that grow over the three films.
Force Awakens throws all that away. There is a rebellion fighting an evil order again, Han Solo is no longer a general but a selfish scoundrel who has fallen out of love with Leia, again. Skywalker is just absent. The premise is to reset all the growth of the previous films, so from the start the new world jars with the old.
The plot itself is garbage. Skywalker has gone missing, presumably because he's sulking, but for some reason there's a map to his new place (partly left in R2, like he was making sure everyone heard him slam the door on the way out of the room). Instead of dealing with that our heroes spend most of their time being bounced around and redirected by things not relating to Skywalker, eventually a new planet killer is abruptly dropped into the film, after that's dealt with the plot such as it is is resolved by two droids turning on their maps.
Star Wars is above all else a masterpiece of pacing. Slow peaceful moments of exposition and haunting shots of the exotic locations, flow into rapid action sequences capped off by breakneck space battles. Force Awakens always runs, it never takes its time and never sprints. The closest it gets is Rey's sequences on Jakku, but they were tragically at odds with the quality of the rest of the film. Dialogue is rushed as everyone speaks as quickly as possible, often while being chased. The briefing sequence, a classic suspenseful part of the saga - the calm before the storm - is instead a rapid fire sequence of bad in jokes and back patting. And as a result the film has no high points, everything happens at the same pace, there is no contrast.
The action, while okay, was also rushed a long at the same running pace. Basically, our heroes have to get somewhere and stormtroopers get in the way, then they get shot. There is no moment like Luke and Leia swining across the chasm, or the sailbarge fight over Carkoon. There isn't even anything up there with the (entirely legit) pod race in Phantom or the (kind of silly) arena fight in Attack of the Clones. The flight sequences are better, though the slapstick comedy of the Falcon bouncing off things makes me cringe, yet they are a far cry from the breakneck space combat of Hope and Jedi*.
Likewise the fantastic shots of the previous films is gone. There's no emotional piece like Luke looking at the twin sunsets. There's no dramatic shots of the scale of machinery like the various Star Destroyer fly overs, or the Falcon entering the Death Star. There is one exception to this, the truly fantastic opening shot, but alas the rest of the film did not live up to it.
Force Awakens seems far more interested in making Star Wars jokes than being an actual Star Wars film, to the point that their planet killer's name is one. The story, little that there is, serves as an excuse for three (admittedly likable) kids to play with a bunch of old Star Wars props and characters for two and a half misspent hours. The world is not advanced, it's reset and jumbled. The film is not made like a Star Wars film, it's a another poor J.J. Abrams film with things from Star Wars in it.
And what annoys me the most is that I wanted to like it. It's got decent special effects, and lots of women in it, and I really can't complain about the idea of more Star Wars. But it's a bad film, and it's a bad sequel to Star Wars.
*This is entirely forgivable, as Hope and Jedi still have the best flight combat sequences you can see on film.
