The movie was very true to the book - not completely so, but mostly so. The musical score was perfect, and supported the themes and emotions in the movie wonderfully. The photography, locations, and special effects were all exceptional. The characters were well played, with human frailties and nuance, resutling in some good humorous moments in the midst of this tale of a bleak time. And, just as in the book, the action slowed as it reached the mid-point of the tale.
So, yes I am eager to see the final installment, yes I would watch this again for the music, the visuals, the characters, and the plot, but I also somehow did not leave the movie thinking "wow!" to myself. This movie is a technically perfect incomplete tale, and thereby lacks the resolution we all crave at the end of a tale.
I think this movie will be best as the first film of a double feature, with the audience able to see part II after a bathroom and popcorn break!
