Scots and Alc
the "social commentary" was there but minimal at best. So while I can see you APPRECIATED THOSE THINGS YOU POINTED OUT, it was not done so in any depth in my opinion.
Also About the aliens;
I found it to be incredibly stupid that a race as advanced as ones being able to travel faster then light, could be content with eating cat food, and living in the ghetto and not rebelling sooner.....
Even the strongest most advanced of civilizations need a leader, and that they didnt have.... (see 75th answer)
And Scotsman is right. If you look into the history of the different entities in south Africa, shit like that actually happens....except they're not from another planet
