Apparently Episode 8 will be written and directed by Rian Johnson, who doesn't have a lot of movies under his belt, but is known as a brilliant auteur. His three movies so far are Brick, the Brothers Bloom, and Looper.
So if you want to get a sense of how Episode 8 might go, check them out.
Brick is considered the best of those, and is very heavily stylized, taking a lot of fast, close cuts and using them to put a hyper-noir style onto a high school setting. It's great.
Looper does that, but less so. It's a time travel based noir. And his interpretation of how to explain the science in a science fiction movie is... pointed.
