I'm betting it'll have "Warcraft"-type success...
Horrible sales and criticism in the US
...But millions of dollars surpassing the budget, internationally.
The Valerian "franchise" has been around since the 1960s in European publications and other media (France's Saturday morning cartoon). That hype alone will make money from that part of the world.
Here in the US? "DuuuuuuH! It looks like Star Wars, it stoopid! it bombs!"...totally clueless that THIS comic was a major inspiration for Star Wars to begin with.
