Alien invasion stories have been done to death. Still, this short (~20 minute) short film by Neill Blomkamp (District 9, Elysium, Chappy) is pretty good, if really rather disturbing. Normally the aliens show up to take some resource or other (water or geothermal energy… you know, stuff that a species with fusion engines, warp drive and the ability to easily raid the rings of Saturn would somehow have a hard time finding), and have little interest in Man apart from seeing us as an impediment. Here, it seems the aliens have an active dislike of us, and as a result do some pretty horrible things. Graphic language and images, so, you know, show your kids.
The aliens are some sort of reptilian, but with a whole lot of Black Goo that seems to be the entirety of their technology. Nanotech goo, perhaps. “Oats Studio” is going to be releasing a number of short films, but of different stories and topics. “Rakka” here does not tell a full story, but seems like it could be expanded to feature length.
Bonus: Sigourney Weaver FTW.
