Eh, I think reactions will be different for generations to come who will be able to watch the entire saga one episode after the other. I mean, yeah, they might have expectations between each movie, but the time for them to build up any expectations will be hours/days/weeks rather than years to decades like many of us. Sure, not every kid is going to like it, but there are going to be kids who love it too.
Considering Abrams also produced the Last Jedi, I would be really surprised if JJ goes in a different direction that is his “original vision”. I guess we’ll see in a year, though, and I guess this debate can never really be resolved until then either.
