I don't know about that since Godzilla 2 is already being pushed forward, but they will definitely need to revaluate their marketing campaigns in the future. With a $190M budget I'm sure they were expecting much more from Kong and while a $50-$55M opening wouldn't be great, at this point they'll just have to accept it and move on. I see a $40-$50M opening myself, and no matter how many monsters they put in Godzilla 2 it's bound to drop from the last one as well. Godzilla 2014 was so divisive that I wouldn't be surprised if it went sub $150M. They have also waited too long to release it in my opinion.
