I really liked the first book (or should I say "the 4th"? Heh...), but this one I liked even more. Perhaps because the movie itself was my favourite one in the original trilogy. Certainly also because the asides, this time, were used more often to reflect the action, and this seemed to fit better. Some of the characters (and even the monsters!) are given more thoughts, which felt both amusing and justified.
As usual, I confess to being quite the Shakespeare nerd in my own ways, and trying to match the retelling with lines from the Bard's plays was a really fun game. "Exit: pursued by wampa." I should have sensed it coming, shouldn't I? (For the record, I didn't, and it was a nice surprise.)
