This is a book that occasionally offers an interesting idea but more often than not stumbles around Science Fiction more than providing an introduction to the study. At times it seems like the author is more interested in name dropping books and authors than providing a coherent thought. Naturally, most of these authors and books appear with little explanation with why they should be mentioned. The author tends to have a single tracked mind even when he tries to provide multiple points of view on a subject, a paradox that fits nicely into the single tracked conclusion. Speaking of the conclusion, the author gives one, literally one that simply presents his opinion. What's worse is that the author often writes in assumptive ways. To the author conservative and liberal are black and white beliefs, the prior being racist, sexist, and bad for science fiction and the latter being open minded, inclusive, and visionary. While at times this binary has been true, binaries are not complex enough to provide a fair representation—a belief the author seems to agree with, but often falls victim to. In the politically charged sections of race and gender, this designation of conservatism and liberalism is particularly concerning since the ideal would be that both belief systems accept race and gender equality. The biggest issue is that stereotyping political ideologies is only the beginning of the issues for this introductory book, which is steeped in assumptions and single tracked acceptance of complex issues. Despite my criticism, the book still manages to provide a decent introduction. Its short comings allow just as much of a discourse as its strengths. Considering how difficult writing a good book on theory is, the effort must be given some credit that the author clearly cares about the genre and is doing his best to introduce it. While he may not succeed at providing a good introduction, he does not fail at providing an introduction. As long as this book is read to be discussed, it can be beneficial, but a reader should be wary of reading this book as an authority.
