Ooh. Good poem.
I agree about the scream, it takes away from the gravity of Achebe's message. I never read this poem, but I like way he deepens the vulture metaphor. It's terribly sad as well. The rest was done quite well. Actually, by the end I forgot I was watching a flash because I was so into the reading, but for the beginning when I was paying attention, I thought the visual aids were very effective.
