I read Brave New World for English literature, and it really made me want to read more Dystopian literature (I soon afterwards read 1984, Lord of the Flies, The Handmaid's Tale and Fahrenheit 451).
I particularly liked the beginning. It was so strong, throwing us into the world and the absurd idea of producing people in a factory. (It's a very nice way to give us insight into the world we've just entered, with its ridiculous caste system). Unhappiness is cured in the society, but is it? (Is it not worse to be forbidden to feel depressed?) The start was very interesting, but especially the middle part worked not so well for me. The story seemed to drag a bit on that part. The ending again, was stronger.
Personally I liked Brave New World better than 1984. I would definitely recommend it.
