Even if you didn’t care for TFA and Rogue One you can’t deny Episode VIII has a lot of potential…ESB like potential.
Rey and Kylo Ren’s training (first time seeing a Dark Sider being trained in a SW film)
Finn trying to fit into The Resistance
Finn possibly finding out Poe shot his friend
Phasma going after Finn
Knights of Ren
Leia and/or Chewie confronting Kylo Ren
Possible learning at least something about Rey’s past or Snoke’s identity
The possible power vacuum left after the destruction of the Hosnian System
Learning about the ancient Jedi
I would be surprised if the film was anything less than great.
You forgot the obvious - Luke mofucking Skywalker, Jedi master.
