Here's the thing the DCEU has never had a failure all the films made money it's just until Wonder Woman they didn't make what insiders thought they would and Hollywood is like hardcore gamblers. Meaning even when they win they always look at the table and think of the money they didn't win because they bet too low in their opinion. But then came WW and it was a hit across the board it was a critical hit, the audience loved it, and it did better than originally thought it would win in every way. Because of that big win they have rightfully put more focus on WW in the Justice League campaign but now we have film promoting a strong successful female hero who in most scenes is standing next to a character played by an actor accused of terrible allegations involving women. So you possibly now have fans and general audience members who will say I'll wait for WW2 to show my support and skip Justice League. Sadly it does seem like the DCEU is cursed sometimes because they never seem to be able to catch a break.
