The Valerian movie adaptation may feature a leftist metaphor for immigration

The new movie based on Jean-Claude Mezieres and Pierre Christin's Valerian & Laureline, Space-time Agents series hasn't officially been released yet, but some advance reviews certainly have, and Time Out's review has quite an eyebrow raiser. Towards the end of the article, they say that:

...the climax is built around a notion of intergalactic humility (toward immigrants, in fact) that feels decidedly otherworldly.

Indeed! Director Luc Besson's already proven himself one of the most naive leftists you could possibly find, especially after the bloodbath at the Charlie Hebdo offices 2 years ago, when he penned a letter blaming "economic deprivation" for radicalization of Islamists, not the religion itself. Coming as it is after all the horrors France experienced in the past few years, that sure is pretty considerate of Besson, I'll say. Uncontrolled immigration is exactly what's injured France, and Besson has the gall to inject that kind of propaganda into the film? It's shameful. If he's injected leftist propaganda, then a better title would be Besson and the Empire of a Thousand Propagandists, because that's where he and his ilk practically come from.

If Besson thinks he's paying tribute to the old comics, I'd say he's only embarrassing them. I can't feel sorry if his Europacorp studio's fumbling financially now.
