Typically, i am the sort of person who likes to see a book transfered into film page for page with no deviation from the original plot. However, this has got to be one of the few exceptions and one movie i thoroughly enjoyed. This film compiles a classic with a few spins and connotations that bring it into the 21st century and up to date with what modern audiences expect to see.
Maybe it is not the same classic story, but really, you need to appreciate that directors often want to take a different approach than the author and this definitely paid off. Another good example would be Charlie and the Chocolate Factory - Another Dahl book. Many loved the book, and the new film has been an outright success despite very drastic changes. This film is reminiscent of that kind of success, although not as widely acclaimed.
The stop motion type of filming is brilliant when the film industry seems to be endlessly pumping out similar CGI and animations that don't contain that same imperfection and man-made feel. If you're willing to try something new, and expect a slight slant on the original i'd give this film a try! Trust me, it's worth a watch.
