Valerian is not an international disaster it's a disaster in the english spekaing countries (UK, USA/canada and Australia who considers themselves as the center of the world) where the critics and local distributors doesn't accept the concurrence of a "french produced" blockbuster.
Valerian was first at the box office in opening day/week in France, Russia, Belgium, Poland, Spain, Ukraine, Hong Kong, Sweden, Turkey, and most of european eastern countires...
After the week end the total gross will be around 140m $ and the film still have to be launched on huge market like : China, Japan, South Korea, Italy, Argentine,....
When I see that Valerian is the "Bomb of the century" when it will make between 250m and 300m $ total Gross for a budget of 150m (after tax credit from the french state)....
This year alone Ghost in the shell, Monster Trucks or King Arthur will do far worse than Valerian.
