No, i don't think that the leading character of the biggest franchise on earth outperforming them speaks to anything.Vocal online minority indeed, I think audiences spoke with their money. In an age where Iron man solo out performs Batman and Superman together I think that speaks volumes as to how general movie goers feel.
Batman v Superman still did almost 900 million.
We’re off Snyder’s weak ass Superman.
I knew it was up when nobody cared about his death in BvS lol.
and I think it’s clear as day that audiences just didn’t take to the interpretations of the characters and in particular Cavills Superman.

2 of the most iconic superheroes of all time. Sharing the big screen together for the first time couldn’t crack a billi crazy.
