I haven't read the book (yet), but concerning the film as it is, I can assure you that it is very well made. You'll get one of the best period dramas (I wouldn't go all the way with "best ever", but then again, I don't often use extremes to describe a movies) that you have seen!
Of course you have to be open to this kind of movie. Meaning, that if you're more likely to watch Bruce Willis in Die Hard or can't wait for the next Steven Seagal movie, this might not be your cup of tea! There is a strong possibility that you won't like (to watch) this movie at all.
So if you have seen period dramas and like them, than watch this one too, if you haven't watched one yet, than this can be a perfect movie to start with (although some might say, it's downhills after that ;o) )
