Basically this is a picture book for horror/monster movie fans. On that level it succeeds admirably containing a wide range of stills and movie posters -the latter often being better than the movies they are advertising. The short text accompanying each picture manages to be informative, sometimes critical, sometimes funny which is pretty good going when the entry is less than 50 words long.
For relative newcomers to the genre, this is a good, albeit far from definitive, guide providing a more than ample selection of movies you'll want to watch. For the long-time monster fan like me, it's a great piece of nostalgia with a complete list of all movies mentioned (and a list of names -mainly actors and directors) which is great because when I have a bit more time, I'm going to go through that list, count how many I've actually seen, and try and check out the ones which seem interesting from the remainder.
Landis loses a point for not including a section on monster plants like one of my favourites 'Matango, Fungus of Terror', though he does mention 'Day of the Triffids'.
