morolf: There's nothing wrong with them...I actually quite enjoyed the War of the worlds movie from 1953.
But there's no need to recycle that material, certainly not in such a pseudo-edgy way as in that Blomkamp video.
And realistically, humanity probably wouldn't stand a chance against alien invaders.
The 1990s tv show Outer Limits did this quite well in several episodes (even if they were deeply depressing).
How is it edgy? If humanity did encounter an alien race, there's a chance that race could be benevolent and share it's technology (like Star Trek), but there's also a chance that alien race could view us as less than rats, deserving only of enslavement and extermination.
