Contains spoilers but I’m saving you 2.5 hours of your life you won’t get back.
Valerian is a charmless character and thinks himself imposing physically on his underling so that she can’t move is not only appropriate but endearing. For some reason this stunning woman whose every line is 100% sass doesn’t slap him, because when she says no she really means yes. That might cut it in France but it doesn’t apply in many others places! I ended up fast forwarding through their scenes their relationship was so utterly unconvincing.
Weak plot, unsympathetic and one dimensional leads, clichéd military bad guy commits genocide and it’s quite obvious after seeing his first on screen interaction with said (beautiful, gentle, wise cliché) alien species, but leads save day and boy gets girl for unknown reasons.
It’s very pretty but like another reviewer said, just use it as a screen saver. It’s The Fifth Element mashed with Avatar. If you like action, and lush visuals knock yourself out. It you like a little more plot, ethical dilemmas and less black and white like the real world, look elsewhere.
