Let me make it easier for you, here's what I said in post 48:
It didn't flop, but it sure didn't make anybody laugh to the bank either.
You can consider 550 million a failure very very easily. For one thing 60% of that came from over seas where the American distributor doesn't get as high a cut as they tend to in America. For another thing only 50 million of that was the first weekend in America, which is when the distributor gets their highest cut. Given how long it took the movie to make that much money and how far the distributor's percentage shrinks as you get deeper into the release it's highly unlikely that 550 million in grosses actually gave Universal the 240+ million they spent to make and advertise the movie. If you don't make back what you spent it's a failure, regardless of how sexy the grosses look.
Whether or not you liked the movie has nothing to do with the simple FACTS that the movie didn't make as much as Universal thought it was going to and must be considered at least a minor financial failure. I've enjoyed many many movies that failed, some just barely like Kong, some spectacularly like Brazil, it happens.
Actually, you DID say that. From post 48:
We get that because it is 100% true. Kong was not a huge hit, indeed it was almost a terrible belly flop.
