Re: The box office "bar of success" for Batman/ Superman.
WB marketed the **** out of MOS and they'll no doubt up the ante with this next film. However, it's way too early to say. If I had to put a say in it:
$990 Million if it sucks
$1.1-1.2 Billion if it gets a MOS like or slightly better critical reception
$1.5 Billion if it gets very positive reviews/critical acclaim.
Again, just speculation on my part.
