Query: Fantastically animated production

This is a beautiful movie with wonderful animation and engaging characters. But under no circumstances watch it with the intention of comparing it to the book by Robert O'Brien. Book and movie are a far cry from each other, and you will only end up disappointed if you are a fan of the book.As a stand-alone movie, The Secret of NIMH is a wonderful production, one of the best products of Don Bluth's career (personally, I believe An American Tail comes in equal). There is just the right amount of action, adventure, romance and good old-fashioned courage. There is enough in this to entertain kids of all ages (I'm 26 and I still love it).This movie is a joy to watch, but not in conjunction with the book. One may be loosely based on the other, but they are two separate entities, don't think that they are not.
