The movie was spectacular.
It's everything that 99.9% of us Star Wars fans wanted. It won't please non sci-fi fans and it'll leave out those 0.1% that couldn't be satisfied anyways, but in the whole it's a spectacular movie.
Yes, the plot is very similar to episode IV/VI with the super-base being destroyed, which is completely okay because after the prequels most of us were wanting to
feel at home.
Instead, the diversity is in the characters, the careful mix between CGI and real-life props, the well-placed humor, the constant nods to the previous movies and the fresh soundtrack.
This is hands down very close to the best Star Wars movie that could have been made, and the top reviews, groundbreaking ticket sales records and hordes of people watching the movie for the second time in theaters is proof of that.
Kylo Ren is the the best Star Wars villain yet, IMO. Adam Driver is excellent at interpreting a deeply conflicted, insecure and immature Force user who went to the dark side and is still struggling with it. Much more than Anakin who went from trying to save the Galaxy to slaying innocent little children in an instant with Hayden Christensen not being able to show a lot of emotion throughout the whole thing.
As for what I think of the stuff the movie leaves in the open:
1 - Finn is Force-sensitive. He's not on a Skywalker level of affinity, but I think he will learn the ways of the Force, at least in order to become a stronger fighter. And I think he even may learn from Leia or even Maz Kanata (not being Jedis doesn't mean they can't teach him a thing or two about the Force).
In Star Wars, the Force is used as the reason for almost everything that is unexpected and unpredictable. I think Finn's affinity to the Force is what made him break from his mental conditioning, contrary to all the other tens of thousands of Stormtroopers that have been successfully brainwashed by Hux's methods.
2 - Supreme Leader Snoke is Darth Plagueis, Palpatine's former master. When Han Solo tells Kylo that Snoke is just using him for his power, Kylo answers that's not the case, that Snoke's way is the correct one because "Supreme Leader Snoke is
Wise". In ep. III, Palpatine asks Anakin if he knew about the tragedy of Darth Plagueis:
The Wise. He tells Anakin that Darth Plagueis had been studying the Force in ways to bring beings back to life and how to create beings from the Force itself (strongly implying that Anakin's immaculate conception was a work of Plagueis). He then says his disciple killed him in his sleep. But I think Plagueis survived, got heavily disfigured by the attempt (which we can see in Snoke's projection) and escaped to the outer rim in order to recover, hide from Palpatine, wait for his next chance to control the galaxy and keep experimenting with the Force, which is how....
3 - ... he
created Rey. I don't think Rey is the daughter of Luke or Leia. Without training, Rey was able to beat Kylo at his mind trick and at force-pulling Anakin's lightsaber. She's also a very skilled pilot
and shows a genius-level of electrical and mechanical engineering, being able to fix the Millennium Falcon within minutes, which Luke was never able to meddle with.
The only other being that approached Rey's affinity with the Force was Anakin, which is why I think Rey is also a product of
Force Conception.
Besides, if they ever want to present a plot-twist that even approaches Ep. V's "I am your father" scene, what better way to do it than to have have Snoke telling her "
You have no father, you're my creation, like Darth Vader before you"?
"Starkiller fired its first shot at Hosnian System, now let's wait Thousands of years for the ray burst to reach it"
During the meeting before the attack, the Resistance members clearly say that the First Order found a way to put an energy beam
into hyperspace, which is how they can attack any planet in the galaxy within
minutes.
