I think this getting Aquaman 2's release date would actually be a good choice. Shazam wouldn't get any of the PLFs in December, so while it obviously wouldn't gross as low, it would be like Matrix Resurrections where it loses a big revenue source because the big dog is taking up all the major IMAX/Dolby showtimes. March is still pretty competitive, and Haunted Mansion could be stronger than expected direct competition, but it's still no Avatar.
