Except that we don’t have the Rebels vs. Empire again. Not really. They are indeed going for that feel, but in the OT we had a galaxy spanning empire and a scattered rebellion. In the ST we have a beheaded Republic, a cut down resistance, both in opposition to the invading First Order. So unlike the OT where the government of nearly every world is against you (because they are controlled by the Empire), now there are allies everywhere, and the Resistance can work to unite the planets trying to resist the First Order take over. While the fighting parties are very similar to what we see in the OT, in the OT that was one fleet of a much larger navy and in the ST, we can’t be sure how much larger the navy is than what we see (and in TLJ a lot of the FO ships were destroyed or badly damaged). So on the surface your argument seems to make sense, but when the full situation is laid out, the comparison falls flat as there are too many differences and too many ways the story can go that can be completely different in the third act.
Maybe not technically, but they’re going for the feel alright, and that’s what I didn’t want. The Republic isn’t just beheaded it seems, it was totally wiped out in one shot. According to C3PO, the entire fleet was destroyed in that one shot by SKB.
Also, the resistance is totally destroyed, leaving just a handful of folks in the MF. They even start calling themselves “rebels” by the end of the film.
I hope they take the story in an interesting and new way in Episode IX and flesh out some things.
