which I think is the impression of most people. But while most not that impressed okay movies get a rotten rating, with this one people are clicking on fresh. Hence why we are at 50% from top critics and 77% overall.
A movie that has 6.5/10 from critics is pretty much considered "average/ B or B-. I don't think there is anything weird with being "nothing impressive" and 6.5/10. And 6.5/10 movie getting 77% Tomatometer All The Time. Like, do people expect a movie with 6.5/10 to get Tomatometer in the sixties or fifties or something?
Secret Life of Pets: 74% and 6.2
BFG: 72% and 6.7
The Shallow: 76% and 6.5
The Conjuring 2: 80% and 6.6
And Ghostbusters: 77% and 6.5
Pretty consistent I think.
About the Top Critics, I can say that they are actually harsher when giving AR than when giving Fresh/ Tomatometer rating, hence the 6.2 AR and 50% Tomatometer among Top critics. The AR among all critics and Top critics are quite insistent (6.5 and 6.2), same for other movies too: Pets (6.2 and 6.5), BFG (6.5 and 6.7), The Conjuring 2 (6.6 and 6.6)
However there's a great discrepancy between Top critics' Tomatometer and their own AR. A movie given 6.2 (which is very much aligned with all critics' AR) by Top critics usually don't get 50% Tomatometer.
The Shallow: 5.9 AR and 66% Tomatometer (Top critics)
Neighbors 2: 5.7 and 62%.
Both have lower Top Critics' AR than Ghostbusters but have higher Top critics' Tomatometer (Ghostbusters has 50%).
If I were a SJW I'd probably say that a few (3 or 4 maybe) out of 12 Top Critics giving Ghostbusters a Rotten score actually have an ax to grind and intentionally do it despite giving it an average score. But I won't say so because top critics, like all critics, have different requirements for Fresh and maybe some happen to have very high bar for a movie to earn a Fresh score from them. But I don't think we can prove that critics happen to click on Fresh because of political agenda either, because as I said, all critics' AR and Tomatometer and Top critics' AR are very consistent, it's just that Top critics' Tomatometer is abnormally low for a 6.2 AR that they give the movie themselves.
