Hotel Rwanda vs. Sometimes in April--two films made reasonably close together both about the genocide in Rwanda--I suggest watching both, but there is a major difference in them and I want to discuss it.

I actually took a 1/2 year social studies elective at my public high school, junior year, called 'Holocausts'.
The majority of the course was of course spent
discussing the Nazi Holocaust of WW II.

There was also a portion of the course about Pol Pot and the Khmer Rouge in Cambodia.  And we discussed more broadly how holocausts come about and what could cause societies to kill a group of people.
