Worst movie of the century so far?

I would vote for Valerian and the City of a Thousand Planets. When Cara Delevingne isn’t the worst actress in the movie, you’re in trouble. Rihanna was somehow worse in this than Battleship. Another candidate for worst movie.

So I am grading on a curve for money wasted. It would be easy to pick a low budget shitty movie, but with a Budget of $177,200,000 what a waste of effort.
