Actually a pretty decent film. Not comparable with Besson's The Fifth Element, which was far, far better, but Valerian was good. Just good. No masterpiece, 'cause therefore it was too ... I don't know...not interesting enough I guess. All the characters, the humor and the art direction in The Fifth Element were exactly right. Here they were exactly not right. Well, except for the visuals. They were stunning.
Oh well, it's simply a very entertaining blockbuster. I liked it.
