They’re not in line with rules that people have established based on the previous 6, sure. But there isn’t anything that directly contradicts with what’s actually in the films. It’s only rewriting our perceptions of the universe, not the films themselves.
It’s basic good storytelling to bring the audience along and not suddenly and radically alter the rules. It’s not that audience has established rules but rather took them from the previous material.
No doubt in additional stories various rules are amended or expanded upon. But it’s important to bring the audience along. If the accepted rules change significantly with no good reason, you risk losing the audience.
Thus with Rey many of us are thinking: this is radically inconsistent with what we saw and liked in previous movies.
Some, like me, were hoping for some great reason to appear in E8. Late in TLJ, Snoke basically tells us the reason is the Force forces itself upon people in search of some kind of balance. Even if we choose to believe the Snokester, many of us think that’s lame.
I didn’t like Anakin as a vergence because midichlorians either or the prophecy stuff. All that is something like a precedent for Rey. Introduced that way, I bet more people would have been on board. And recognizing that, I can honestly say that’s still lame.
Many don’t think the rules were altered radically. Most probably don’t think the rules were altered at all. I remember I saw TFA with a big group of people, mostly casual fans. I was the only one who had a problem with Rey performing the mind trick. They either didn’t notice the inconsistency or didn’t care. Even without the anecdote, I’d guess most of the casual audience isn’t too concerned with the minutiae of who can do what force powers when.
