This number is so large that it makes me question the accuracy. The movie is 115 minutes so this is 77.6m views if we assume that everyone who streamed it watched the entire thing and only watched it once. It looks like the most recent numbers say Netflix has 209 million subscribers. That would mean 37% of the global Netflix subscriber base watched this movie in the first few days after release. That is literally unbelievable.
It isn't directly comparably to theatrical box office numbers, but the total viewers would likely translate to at least the 2nd biggest opening ever for a theatrical release. That would be a ridiculous accomplishment for an original movie. There is not a single non-franchise movie in the list of top 50 biggest openings ever[1].
And before anyone responds, yes I understand that the assumptions I made would impact these conclusions, but the assumptions are working in opposite directions, at least partially cancel each other out, and are mostly just used to show approximate magnitude.
