Valerian is director Luc Besson’s passion project: He wrote and directed it based on a French comic book he loved as a child. It’s also the most expensive independent film ever, with a budget of around $180 million. It’s quite the spectacle, and the plot—involving displaced aliens amidst a multi-species space station—could be a reasonable foundation for a sci-fi adventure or sci-noir procedural. Unfortunately, the acting, character development, and dialogue are simply terrible. Ironically, the only believable character is a shape-shifting burlesque dancer played by Rihanna.
