Well, it looks like Dark Fate is having just that, a dark fate. It has dropped 63% in its 2nd weekend, an all-time low for the franchise. The lowest drop in the franchise from previous sequels was 61% from Salvation. However, the previous film Genisys dropped only 49%. Below are the DBO totals after their first 10 days.
The FBO isn't looking good, either. Its best foreign market, China, is dropping much faster than Genisys did. By its 2nd weekend, Genisys was at $77M. While we don't have this weekend's Sunday numbers from China, it looks like T:DF will finish its 2nd weekend $30M+ below Genisys (currently at $40.5M without Sunday.)
