You're not going to see me defending Lucas's slop, but I think the fanboys have a lot more goodwill for even the worst aspects of the prequel trilogy than they have for Disney right now.
I won't defend either nor step on the judgement of the true fans, etc.
However we are both commenting on a sub branch headed by a comment:
Colossal losses of Disney ...
You mentioned Rian Johnson and his work on Part two of trilogy ?? (I honestly don't bother with anything past the original version of the first film) Star Wars: The Last Jedi.
Regardless of its trashiness in the eyes of fans it still box officed $1.334 billion after a budget < $320 million (according to wikipedia).
Let's agree that it was slop ... but it was slop that made bank for Disney.
I think this kind of analysis basically exemplifies the MBA disease Hollywood has. They think that as long as they can show a profit, things are going fine. But in the meantime fans are catching on and goodwill is being burnt. The fanboys become less fanatical and the performance of future movies begins to suffer.
