I'm not a Star Wars nerd (but I watched Episode 7-9 nevertheless). I think the main weakness of the "Disney trilogy" is that the plot is basically the same as the "original trilogy": powerful evil forces with a death star/planet, commanded by a truly despicable bad guy with a slightly more nuanced henchman, valiant heroes fighting them and winning against all odds - been there, seen that. And the plot twist at the end (let's not reveal it, although everyone probably knows what I mean) makes it even more similar.
