I feel like the movie could have been better if the whole “thermal oscillator” thing turned out to be misleading, and they had to find another way to destroy it. It would have been even better if Finn had begun a stormtrooper uprising and helped destroy/disable the base from the inside (there must be other stormtroopers that think the same way he does–he might even know some).
I feel like the shields were disabled too easily, and the thermal oscillator was destroyed to easily, and the whole planet was blown up too easily.
I also think this movie should have been split into three movies:
Episode VII:
We meet the new cast. We are given some more time to get to know them so that we care about them more towards the end. We actually find out how big the Resistance and the First Order are so we get a better idea of the stakes. The existence of Starkiller Base is revealed, and the base is attacked while the Rebels evacuate their planet. They lose the final battle, and their planet is destroyed. Han convinces Ren to come with him. Luke is found to be absent from the planet at the end, but he leaves a clue.
Episode VIII:
Finn goes undercover to win stormtroopers over to his side. This is kept top secret, and not even Rey knows. Together they discover how to destroy Starkiller Base. Rey, Poe, and Ren search for Luke, and Ren trains Rey. The attack is made on Starkiller base. As Ren, Rey, and Poe storm the base together, Ren turns on them, revealing that he was acting as a double agent all along. He also reveals that Rey is Luke’s daughter. Rey fights and eventually defeats him, though thanks to him, the Resistance suffers heavy losses. Ren was kept ignorant of the fact that Finn was on the base, and it is through a surprise stormtrooper rebellion that Starkiller Base is finally disabled, with help from the Resistance. The Resistance either take control of Starkiller base or are faced with the challenge of evacuating all the stormtroopers on their side.
Episode IX:
There would be ethical problems raised by the Resistance’s control of Starkiller Base. The search for Luke continues, and the trail he leaves seems to be leading in circles. The search for Snoke is also ongoing. Rey has been having visions, and they eventually lead her to Luke’s hiding place. She goes to find Luke but something is wrong. Then she discovers why–Luke is Snoke. He captures her, but is unsure what to do with her. Meanwhile, the Resistance has discovered where Snoke is, but are unwilling to attack until they find Luke.
From there, there are a number of ways it could play out, some of them better than others. Maybe Luke/Snoke could end up killing himself when faced with the choice of killing Rey and/or Han and Leia. Maybe Rey could join him, but then turn on him in the end.
That’s still a bit too much like the OT, but I tried to roughly follow what has been set up so far.
It’s also not really that good, but I would have preferred to see some of those ideas. It would also have spread things out more, which is one of things I feel really should have been done. Maybe that’s just me, though. I’m glad most people enjoyed the movie more than I did. Maybe things will start to fall in place in the next movie, and I’ll enjoy that one more…
