Wasn’t Jumanji one of those films that made more moolah on home video, like Austin Powers? The original had enough clout Sony hyped Zathura in 2005 as a sort of sequel, which it wasn’t really.
You also can’t discount people who saw the original film as kids and are taking their families to see this one. Not much else in family fare out right now. Coco has been out for over a month, and nobody apparently cares about Ferdinand as it’s not Pixar or Disney.
