if you want a comparitive movie, amazing spider-man 2 is a good one, its budget was much much much higher than reported and in the sony leaks it was revealed that sony literally made NO MONEY off that movie
budget from wikipedia
Budget $255 million
Box office $709 million
its pretty easy to see why warner bros is all "were gonna be more hands on for justice league"
there not gonna let this happen again, if it does the dccu is pretty much dead.
