When you buy milk within the expiration date, you don't expect it to be sour. If you sell milk and it’s good one week and sour the next, you won’t have any customers – even those looking to buy sour milk won’t buy yours because it might be good that week - YOU DON'T KNOW WHAT TO EXPECT.
Johnson’s goal wasn’t to craft a good story; it was to divide fans. This isn’t a matter of interpretation, this is a matter of public record and fact (yes it’s on YouTube, I saw it myself and I’m sure you can find it).
So with that goal in mind, he didn't want to put out good quality milk or sour milk, he had to put out "meh" milk just on the edge of being sour without making it all out sour, so to speak. But it had to be milk that was both brilliant and horrible by interpretation, that's the tricky sneaky part.
So how do you do this? Well, you do small things to spoil it without all-out spoiling it... you walk a fine line, so that it is forced to FIT INTO BECOMING a matter of interpretation - some people will taste that the milk is off, others will say it's still good. Both are right. The milk is not 100% okay, nor is it 100% spoiled, it is in between. By design.
So indulge me here.... If someone wrote a story where Hitler saved a Jewish preschool or Mother Theresa opened fire on an orphanage with a bazooka, you would surely think it’s out of character. For it to work in a story, you would certainly want an explanation as to how the person came to that, you wouldn’t just accept it because it’s so far out of character. BUT a good writer could make it work with the proper CONTEXT. Context is EVERYTHING.
Personally, I found all the context I needed to like the film. I liked this better than TFA, TPM and ROTS to be honest.
