I think people here are overly pessimistic about the DCEU films. At least more than the box office to date warrants. You could go through my superhero box office threads, but I'm pretty sure there were some $600M WW type predictions.
I personally think that Justice League will be in the same ballpark as BvS.
Over 300 absolutely dude. I'm not sure about a billion tho. It has a better shot than BvS at that tho because the tone will be considerably less grim than BvS
No families and kids wanted to see BVS again or recommend it when you have psychopath batman and burning superman effigies lol
Hmm. I definitely don't think it's going to drop to $600M WW, but I'd be surprised if it did hit BvS numbers domestically.
A lot of it may depend on if Wonder Woman is well received, but putting that aside, this is still following a movie that couldn't break a 2.0 multiplier despite some of the weakest competition possible, it's less than 2 years since BvS so there hasn't been much time for people to forget their feelings about it, and every one of Snyder's post-300 films have had, at best, divisive WOM. Justice League will have better legs by virtue of the holidays, but I say the damage has been done to the opening weekend, and Snyder directing means the legs will still be poor. A 125/295 run mirroring Deathly Hollows Pt. 1 is what I'm thinking.
Edit: A result like that would probably make heads roll at WB, but I actually think it would be pretty decent in the context of BvS. If the Ryan Reynolds Green Lantern film got a sequel, we'd be discussing the possibility of it dropping over 50% in gross, not just 10%.
