Episode 7 8 and 9 is focus on destroying the first six.

I watched the movie and I thought it was fine. I realized exactly what they were trying to do. They were trying to move away from the Skywalker importance. They also seem to mirror Rey and Anakin path.

Both were nobodies.

Both gave into darkness easily.

BOth are alone with no parents.

It was the Jedi and the events surrounding Episode 4-6 that made the Skywalker line seems special.

However, Snoke said it in the movie, whenever a powerful dark presence rised up, the Force will raise another to balance it.

In the original Six Part Saga, it was made to appeared that everything the Jedi did, everything the sith did, all those thousands of years lead to the culmination of the Skywalker line.

When in reality, It happened all the time and the Skywalkers are nothing special. Episode 8 theme was said by Kylo plenty of time. Kill the past. Let it die, Let it go.

So I am going to predict that Episode 9 will be opened ended, there is no more Jedi and Sith, just Force users free to do whatever they like.

That would also set up for the next set of Trilogy by Rian Johnson to focus on more epics set in the SW universe. That SW 1-6 was just the focus for that point in time but more is coming, more powerful character etc etc.

I can see why they killed Luke Skywalker off too. He anchored the franchise more so than Han and Leia.
