definitely a big issue for Disney with these films is no matter what they did a portion of the fan based would be upset and think they are idiots for not creating the specific movie they wanted made
And if JJ can pull it off with Ep IX to at least make the vast majority of people happy (no way to make 100% since some people will be made just for the sake of being mad) then serious props to him - not an easy task
I will try to go in and just enjoy the film for what it is vs complain about what it isn't - just hope that is relatively easy for me to do
