i think annihilation is more like psychological nature thriller, and the division is more of like a post-apocalyptic action movie? speaking of which, i saw the pictures from the set and it looks pretty much like exactly what i pictured when i read the book so i can't wait to see what they did with the movie. but i feel like the division could either be really good or a complete trainwreck so i'm waiting to see what director and writer they get, although i guess a trainwreck is probably less likely with chastain on board.
