Having read pretty much every thematic analysis of Kubrick's films, I've found that they range from the bizarrely illuminating (Geoffrey Cocks), to the wise-but-stilted (Mario Falsetto), to the fascinating (Thomas Allen Nelson), to the nicely concise (David Hughes), to the TOO concise (Paul Duncan), to... well, this offering from Norman Kagan. The author is clearly passionate - he revels in translating sound effects dramatically to the page, and is eager to describe recurring themes as he sees them - but also clearly misguided, such as where he claims early on that Kubrick "is not interested in Freudian theory". And some passages are just weird, as where Kagan deplores Maurice's violent distraction in The Killing, claiming it would be stopped sooner... with "judo tactics".
There are plenty of very good books exploring Kubrick's films, but this is not one of them. On top of the dedicated works by the authors mentioned above (add to that list Luis M. Garcia Mainar, and the collection of philosophical essays edited by Jerold J. Abrams), I strongly recommend Robert Kolker's A Cinema of Loneliness.
