If you are bored of the Lord of the Rings, this book, an examination of the difficulties in adapting the trilogy into other media, may strike you as a rather pointless exercise.
If, however, you have even a passing interest in the books or films, this is an engaging and opinionated read which is authoratative without being dry and comprehensive without being overly lengthy.
As it is published under the imprint of "Virgin Films" it should be no surprise that the Peter Jackson films take up most of the authors' attention. Dedicated Tolkein fans may be irritated to read the many instances where, in Smith and Matthew' opinion, Jackson has improved on Tolkein's story. To be fair, however, they do admit Jackson does rather bungle the ending of the story, leaving too many characters dangling without their eventual fate being made clear.
A more in depth analysis of the similarities between the earlier cartoon version of LOTR and Jackson's efforts would have been welcome but the book is wide ranging, examining the BBC Radio version and the truly awful Leonard Nimoy song, for example.
With boxes of text containing extra facts and figures, the book does read a little like an extended magazine article. Also, some illustrations would have been nice, particularly to demonstrate the work of Alan Lee and John Howe. In general, though this is an interesting and enjoyable read.
