Indeed, while I (finally) went into the theatre thinking "this is gonna be pretty, but it ain't gonna be Valerian&Laureline", I walked out thinking... Well, halfway differently.
The movie is jarringly different, and I can see how some would dislike the jarring bit. I enjoyed every split second of it, exactly because the movie broke every rule in The Book, 2017 edition. The pacing was all wrong, the character chemistry was all wrong, the story was all wrong from ordering of elements to editing of elements to themes to overall plot to details of dialogue. Gloriously wrong. Excitingly wrong.
Consequently, this was Valerian&Laureline, just as created by M&C. Don't get confused by the introducing of the lead characters as important and skilled government agents (or even as lead characters). The former is supposed to be the dullest guy in the universe, an ugly simpleton only ever warranting motherly or sisterly love, despite his self-delusions. The latter is supposed to be the adult of the team albeit in a kid's body, with histrionics to match the latter when it suits her purposes. The team is supposed to sort of wander through an overwhelming universe they have zero hope of ever comprehending, a universe that only exists in order to be a commentary, while the adventure or mission chiefly involves them staying true to themselves.
The non-Hollywood pacing with super-long intervals between scene changes (remember the 20th century?) is so good it hurts. The gentle spelling out of the simple plot towards the end is unnecessary for the audience as such, but exactly what one would expect the poor thick-headed Valerian needs (in addition to another cosh in said head, as usual).
The "segues into side missions" thing is the one jarring bit that jars me wrong, but only because I can so plainly see what's going wrong there. Each and every of those segues was part of a linear whole in the original L'Ambassadeur des Ombres, with Laureline struggling through one humiliating alien ordeal after another in a monomaniacal quest to track down the helpless Valerian - it's she who dons the jellyfish, but also she who enlists the help of the shapeshifting prostitute etc. As adapted for the movie, the ordeals don't pile up into a martyring mountain, which was the very point of the original.
What would have killed the movie for me would have been the employing of a charismatic male lead. What I'd have liked more of is the inner workings of Alpha/Point Central, with more appearances by the three little informants and more agency to the nonhumans in general. What I regret is that we'll never get a sequel...
I probably wasn't as awake through the movie as I should have been. What Hollywood homages are there besides the Jessica Rabbit bit? What cameos besides the guy who gets thrown out of the brothel?
