The movie "In the Beginning" has not yet been shown in my country and that is why I can not compare the book with the movie. Besides, I don't feel a good book should be compared with the movie it is based on. "In the Beginning" is a wonderful book. It keeps in line with almost everything in the Babylon 5 universe. Characters, dates, places, occurences, it all feells right. Any B5 fan, who has seen all of the show, such as myself, would feel at home. Although it is regretable that gaps in the story arc are filled in movies and books instead of in the show itself, the book is a "must read" for any one who wants to truly understand what led to the creation of the Babylon project, what really happened in the Earth-Minbari war and how it all comes together. Very important info is passed along in the book. The story itself is well written, fluent and enjoyable. I most deffinetly recommend!
