Is the “WW got good reviews because feminism” argument dead?

Actually, Wonder Woman's high reviews are accurate, but Black Panther's reviews are artificially boosted by critics afraid of giving Black Panther a bad rating for fear of being labeled as racists. Just look at the difference between the RT critics' rating and the RT audience rating.

The difference for Wonder Woman is only 4% (92% by critics and 88% by audience). So we can say with certainty that there's a general consensus that Wonder Woman is a  90% movie.

The difference for Black Panther is a whopping 18% (97% by critics and 79% by audience). So its' far from a consensus that Black Panther is a 90% or higher movie. In fact, if we give the critics' rating and the audience rating equal weight and averaged the ratings, then Black Panther comes in at only 88%, which is considerably less than the 97% that critics gave it and which is also lower than the 90% average that Wonder Woman comes in at.

So we can say for certainty that there's a general consensus that Wonder Woman is a 90% movie, but we can't say that for Black Panther because of the huge discrepancy between the critics' ratings and the audience rating. The whopping difference certainly indicates that Black Panther got higher reviews due to artificial boosters - namely, the critics being afraid of being labeled racists if they gave Black Panther a bad rating.
