The Fifth Element and Valerian and the City of a Thousand Planets are widely considered to share a thematic and stylistic universe, with similar aesthetic influences. There are shared elements (ha!) and aesthetics, with Valerian even featuring a shop called "Korbens" as an easter egg to The Fifth Element.
Unfortunately the movie doesn't do it for me, the 90s were a better time.
Once CGI became good storytelling and creativity took a backseat in Hollywood.
Perfect CGI and no-grain 4K (?) flattened the feeling.
