I really enjoyed this one.
It is far closer to the book than I thought it would be, although I could be wrong as it's been 20 years since I last read it.
I have two slight issues, in that the bullies who were fairly prominent in PT 1 were, I felt, under used in PT 2.
Spoiler... Spoiler... Spoiler... Spoiler...
The ending... The survivors remember everything. In the novel, I have a fair recollection of them not remembering.
But those two minor quibbles aside, it's a fantastic film.
