I'm glad I have this book - it's a handy resource when I need to find out if someone ever appeared on the series (though some of the names in the index are out of order - John Lennon, for example, who btw is not THE John Lennon) or in a particular episode.
However, as an "episode guide," it's of limited usefulness; if you happen to remember each episode by name that's fine, but if you are reading one of these entries and trying to figure out if it's one you've seen, good luck. I was really hoping for a brief synopsis of each episode. That would make for a much bigger book, granted, but also a more useful one. We are talking about nearly 300 episodes here - some of us (and even historians) might need a little help.
This might be excusable if the episode writeups were lighter on opinion and heavier on relevant information. "The Guarnerius Caper," for example, is the story of a Soviet violinist whose instrument is stolen, causing considerable diplomatic discomfort. Hawaii Five-O often did episodes about political relations with make-believe nations; this is one of the few episodes that acknowledges real-life politics: the Cold War. Is any of this mentioned in Rhodes's discussion of the episode? Sadly, no.
Thus, as a "critical history," it is even more disappointing than the episode guide. It's a sketchy history at best, and reads more like a fan's personal memoir. Criticism is far more credible when the author tries to be objective; at times it seems Rhodes is writing a love poem to Steve McGarrett (and/or Jack Lord). She makes a catty remark about someone who quit the show to pursue other interests (Zulu wanted to do comedy), and editorializes on the worthlessness of basketball (the show was sometimes pre-empted by basketball during its original run).
She also makes nonsensical observations. For example, she says it was a sad social comment that "The Child Stealers" passed up a healthy Asian boy in favor of a white one. Since neither of the kidnappers were Asian and they were trying to pass off the kidnapped children as their own, it wasn't sad - it was necessary.)
Nevertheless, I do feel the book's a keeper. No one else has taken the time to compile a book like this, and it was sorely needed. While it comes up short both as an episode guide and as a critical history, it's still a good read. There are fewer photos than some of us would like (I'll look again, but I don't recall seeing any photos of Duke or Ben), but many of the photos are rarities, and that was a treat. Rhodes's enthusiasm leaves objectivity by the wayside, but it also gives the book a lively voice that makes you want to bask in the genius of one episode after another. The book was written with care and love, and it shows.
