* If tomatometer & audience score are within 5% of each other, you can trust the ratings to give you a decent indiciation of movie quality.
* If tomatometer is more than 15%+ higher than audience score, it means it's an artsy fartsy movie that critics like and movies don't.
* If audience score is 15%+ higher than tomatometer, it's a fun movie even if it's not oscar worthy. (https://www.rottentomatoes.com/m/old_school is a perfect example)

EDIT: Truthfully, it was the release of these two films (both Dec 2017) that caused the Tomatormeter and I to part ways. Simply indefensible, IMO.

So far as betrayal goes, from the perspective of someone with that background, TLJ and Rogue One are the only two Disney Star Wars films I’d save from a fire, and I’d give it a hard think before I bothered with Rogue One. Nothing about TLJ struck me as “a deep betrayal”, and on the contrary, it felt like a return to the franchise’s roots in a lot of ways, but with enough of a twist that it wasn’t just a mediocre lazily-plotted remake (cough).
I don't have some nostalgia emotions of going to cinemas in 80s, waiting in endless lines for tickets, watching it 30x in a row... its a nice scifi soap opera but not much more by today's standards. But its true I don't care about things like canon and entire SW universe, and neither do folks around me.
