I find it strangely dissonant that you dismiss TFA and TLJ as “nostalgic cashgrabs” and “corporate fan fiction”, yet you say you “loved” Rogue One.
Contrary to your opinion, I thought that TFA and TLJ while they do play on nostalgia, had a lot more heart than Rogue One, which I felt was a soulless assembly of recognizable imagery built around hollow characters.
TFA and TLJ add nothing of value to the saga of I - VI, Rogue One does.
The characters in Rogue One may be very underdeveloped, but at least they’re actual characters with flaws and personalities, and not Cliche Two Dimensional Character #1, #2 and #3.
