I think people need to get rid of those "save by overseas", it's true international market is much bigger place especially china, but please bear in mind, POTC5, transformer 5, aliens or the mummy, through doing poor now domestically, all these franchise were initially doing very good here in USA, the overseas market only then followed up in the sequel.
Meaning, to get your film be successful in at least a decade, you still need to get "approval" from USA audience, the market still the biggest in the world, and have a huge post-cinema lifespan.
To me, film doing good in USA tends to have better overseas, USA's number has huge indirect influence in OS market and OS market react correspondingly.As example for GO, I dont think Get out could make $80m overseas if wasn't doing that huge in USA.
