I can't sleep. Not yet. I know I'll lie awake thinking far into the wee hours.
I can't comment: first of all because I haven't internally processed enough to externally process, secondly, because my family has not seen "PC" yet and I have been requested not to spoil anything.
What I will say (though I am no judge of films, despite revelry in their pleasures) is that, if I knew not the book, I would consider this one of the better fictional films I have ever seen.
