TFA not only ruined the first instalment of the new trilogy by being shitty rehash, but it also made sure the second instalment will be a rehash at least to some degree. I do not think I will even go see Episode VIII. Even if I put the rehash aside, the characters made in TFA are quite boring and unlike-able. There is simply nothing for me to look forward to in new trilogy.
Luckily they are making these spin-offs quite regularly so there is still something left.
I think the characters themselves will ensure the next installation will indeed be a huge disappointment. I can’t see it being anything else. A weak villain, a seemingly obvious plot, a boring heroine and no doubt more easter eggs and dodgy cgi monsters. With an R2D2 ball to finish off.
