I was looking at it today funny enough as I haven't seen it since it released (Can't believe it came out in '04). I think it's still a wonderful film but it definitely has aged graphically. It looked much more impressive back in the day. Still a great film.
The book is a classic. The movie, while well intentioned, misses the mark which was never meant to be hit. Which is to say, the artwork for the book is the untouchable.
