The question was specifically about fans who were polarized and not going, I think this thread alone shows you can both be a hardcore Star Wars fan and still be unwilling to see TRoS, at least in theaters.
If you’re not seeing the latest Star Wars movie in the theater, then I don’t know if you’re a hardcore fan.
To me, hardcore means not only a level of fanaticism, but perseverance and optimism.
I can’t imagine ANYTHING that would keep me from seeing a Star Wars movie theatrically.
I already have a ticket to the 9 movie marathon and multiple showings afterward. That’s hardcore.
