Since I refuse to watch any more John Campea videos (used to respect him, now abhor him) as tit for tat I'll put up a Grace Randolph video--but I'll actually do you the favour of giving some detail on the video so you don't have to watch her if you don't want.
She goes over the very early projections for the opening box office re AQUAMAN, MARY POPPINS 2 and BUMBLEBEE--with the caveat these are very early and unreliable--from the industry at 45 M, 40 M and 20 M respectively.
While these are low numbers, given the crowded Christmas market not so low, and GR sees chance of improvement. A lot depends on a fresh RT score, but like JUMANJI 2 and THE GREATEST SHOWMAN, the stars could align to improve box office over the long haul for Arthur and Mary.
Me personally, I wonder if the studios purposely kept these movies in competition with each other to give themselves cover. Grace observes that they are all troubled in their own way--so I wonder if the studios are nervous how they'll perform. If they were each released at different times against less competition, they might not do any better--but the studios wouldn't have the cover of saying it was due to the crowded marketplace. In a way, the Christmas release allows them to downplay their failures--if the movies don't do well.
