I mean they introduce interesting ideas that aren't safe, but then in the latter half of the film they go back on them and in the end just return to safe ideas.
For example, look at what they were doing with Rey and Kylo, and Luke to an extent. They were introducing a compelling idea in a grey area of light and dark. They toy with the idea of Rey and Kylo joining together to bring the light and dark into one. This is something we haven't seen before and is new.
However, they end up essentially going back on this and returning to light side vs dark side once again, with even Luke himself deciding to be good again. Kylo and Rey are once again in opposition and that grey aspect is ignored. Why introduce something like this when you aren't going to follow through with it?
What I've been saying is that Disney showed some new more risky storypathes, but got cold feet and returned to the dull plotline we have seen countless times.
