Valerian and the City of a Thousand Planets
Valérian et Laureline is one of the foundations of modern scifi, despite not getting much credit outside of France. It was first published in 1967 and has been referenced as inspiration for Blade Runner and Fifth Element - George Lucas has never given a straight answer on Star Wars and Valerian. When making Fifth Element, director Luc Besson brought in Valerian creator Jean-Claude Mézières to do art, who famously told him that "this is shit why dont we make Valerian." Well luckily for Jean-Claude, Luc got to make the film two decades later. If you want a solid scifi romp, pickup the comic omnibus's.
As for the film, it is eye candy first and foremost. The plot, though now somewhat cliche, is fairly solid. It follows one of the comic stories about a space station that is built by all races over all time. Valerian and Laureline are pretty much intergalactic cops tracking down a stolen asset. There is a overarching story about how a war destroyed a native people that is interwoven with the rest of the sub plots of political powergrabs. But I wont go into detail since you can read it on wikipedia.
It does however have some bad notes. It is obviously a late 2010's film because it has its "for 3d" scenes. Sadly the lead, Dane DeHaan has trouble pulling off the roguish smarminess of the Valerian character, but he handles himself acceptably well. Laureline is portrayed by Cara Delevingne who was a bit tough to watch at the beginning, but she falls into the character. The surprise best character is played by Rhianna, who is a shapeshifter for an adult club and serves as a comic foil for a bit.
I recommend it if you enjoy action scifi or just want eyecandy scenes. I started it on a friends plex server then bought the bluray and watched it on my projector with surround sound. Its not perfect, but it is alot of fun.
