This movie is wonderfully shot and absurdly Disney-fied. The personification of the animals and their behavior (plus a script that seems to recycle the same few lines - Earth Day for writers?) is, at times, laugh-out-loud silly.
Forty-four minutes on a TV hour would be more than enough of this - and free!
Many reviewers have read the book and made comparisons or assessed how well the book is reflected in the movie. I haven't read the book, so can comment only on the movie on its merits - and it was great.
This is one of the most intriguing, compelling, and ultimately rewarding movies I've seen in a long time if not ever.
If you like mysteries, layered and realistically portrayed characters, a bit of action and suspense...and more...this is one you have to see.
I'm not sure which movie many of these reviewers watched. Little happens and there is even less point to the story. Worst of all, no character emerges as particularly interesting (except maybe Bardem) or sympathetic...and there is simply no chemistry between any of the characters. In a word: blah.
