If you're at all interested in filmmaking as an art or a craft, read this book. Murch is one of the few contemporary film theorists with a platform, and you'd be hard-pressed to find an editor who hasn't been influenced by his work. Film editing may be "cutting out the bad bits", but it takes a lot of thinking to know which bits are bad. Murch has certainly done a lot of thinking about the subject, and his thoughts are worth your time.
