You have to look at the film holistically to understand.
To understand what? That the plot and character developments didn’t match percieved expectations?
Just because it doesn’t, that doesn’t make it bad nor does it mean hardcore Star Wars fans were intentionally jerked around.
Of course not, that would be silly. If I’m not explaining it well check out the David Stewart videos. Maybe you just won’t see it. And that’s far less interesting than you understanding but disagreeing with the argument.
The most clear “evidence” of the “jerking around” thesis is, that TLJ’s story seems to be driven by the twists, rather the twists being driven by the story. Almost every twist is a variation on an OT story thread, as if RJ wanted to avoid being accused of rehashing the OT by doing the opposite. I’ve said this before, but TLJ is not as original as many seem to believe.
