Actually I heard about this film quite awhile ago, but avoided it because I assumed it would not tell the true story of the atrocities that took place in Rwanda. I saw the PBS special Ghosts of Rwanda and it affected me deeply. I do understand that there was indeed a Hotel Rwanda that housed Tutsis, but I'm not at all certain of the details. Nonetheless, the movie did have a Hollywood cast and did a fairly good job characterizing the senseless genocide.
Though I preferred the PBS special, I would definitely consider this flick recommended viewing. Especially, if you are not at all familiar of the massacre, it will open your eyes to the realities of this terrible event.
