I never saw an ad for this movie. Not one.
Also lets look at last weekend-
New York had flooding issues.
Here in my city the State Fair opened and Prairie View AM & Grambling played.
The last weekend of regular season of baseball.
There was too much stuff going on for anyone to be concerned about a new movie with POC leads that had little to no promotion.
Along with some of the same folks who scream for new properties with POC leads-trashing or making every excuse to NOT go see those movies that they cry about.
