poor test screenings
From wiki
In April 2018, it was reported that the film was scheduled to have several weeks of reshoots in late 2018 or early 2019, following poor test screenings.[24] Due to Ridley's commitment to Star Wars: The Rise of Skywalker and Holland's to Spider-Man: Far From Home, the reshoots were not able to commence until April 2019, with Fede Álvarez directing them. These reshoots, which took place in Atlanta and lasted through May, added an additional $15 million to the film's budget
