If you're feeling good about the world in general, go see
Hotel Rwanda. All that warm heartedness will vanish.
You should see it now, because it's only one decade too late.
And when you're done, spend 2 hours researching Sudan so in a decade when the
Hotel Sudan flick comes out you'll be like "Oh yeah, I remember that."
