The opening portion felt like a documentary, complete with information flashing across the screen and small graphics trying to explain things, which I honestly found irritating. There were moments when I considered stopping altogether, but I'm glad I didn't because once it gets underway, it’s genuinely enjoyable. It seems that aliens have been observing television broadcasts and decided this time around to bypass the usual military reception in the United States, instead choosing South Africa. Their spacecraft hovers over Johannesburg, carrying a group of creatures—they resemble characters from “Predator”—seeking a place to reside. The answer they find is "District 9," a shantytown resembling a favela where they’re left to struggle and survive in harsh conditions. However, what truly captures humanity's attention is their advanced weaponry, and when a particularly violent method of circumventing that security measure is discovered, the situation becomes increasingly dangerous for the extraterrestrial visitors. With the goal of relocating this sizable population, a seemingly civilian operation headed by “Wikus” (Sharlto Copley) is tasked with organizing their relocation—a process that predictably doesn't go smoothly. During this effort, he contracts a fluid that begins transforming him into one of them! Now rejected by his own kind and hunted by mercenaries seeking to weaponize the aliens’ technology, he must depend on these creatures if he wants to live or find a way to reverse the effects. After getting past the slow start, the film moves along at an engaging pace thanks to Copley's performance and some very believable visuals depicting a makeshift ghetto that serves as much of a commentary on their treatment as it does a backdrop for the more typical video-game action sequences. At times, it prompts reflection on who is truly more human, and though presented within a science fiction framework, it poses quite moving questions about mass migration that resonate with issues closer to home. Don’t give up on it; it's worth seeing.
