The plot stumbles along, but the movie’s sheer spectacle and chemistry of its cast and their badinage makes Valerian a necessary summer watch.

The visual sugar-high never killed anyone, and as far as escapist blockbusters go, Valerian and The City of A Thousand Planets is as imaginative and spectacular as they come. Just keep your mind switched off and put your 3D glasses on.

Fans of 3D-films, kids and teenagers are going to love Valerian and adults too will enjoy the film if they keep their expectations low, approaching it just as a stress-free visual entertainer.
