OK, I don't go the the movies a lot [1] so am generally unaware of much of what is in theaters, but I do watch a lot of TV live (as opposed to on DVR) on channels that have ads and on which studios run lots of ads for the movies that they expect to be big, so I'm usually aware of what is opening that the studios are expecting to be big.
I don't recall ever hearing anything about this movie before reading that article. Was there something anemic about their advertising in the US? Or were the ads just so forgettable that I did see them but completely ignored or forgot them?
[1] My complete movie theater history for the last 20 years: American Beauty, Gladiator, second two Matrix movies, the three Lord of the Rings movies, the Star Wars prequel trilogy, Wild Wild West (by accident...was trying for Star Wars and went into the wrong theater), How to Train Your Dragon 2, How to Train Your Dragon 3: The Hidden World, and Avengers: Endgame.
