The book is so much better but the movie is still well-done.
The film's novel by Issac Marion is my favourite book, so its fair to say it would be difficult to do it justice in a motion-picture sense.
You may not devote the time to this film because the description might remind you of a certain supernatural love story series... and I can assure you, Warm Bodies is not at all simular to Twilight.
One of the best soundtracks to a film with a variety of songs that still manage to fit the storyline and atmosphere.
Although the characters here are lacking the development and insight that the book provides it is still a movie you can appreciate for it's ability to give some vision to the story.
