Very Informative
First off, you don't read a book like this on a lark. It's an academic study, and you have to have an interest in the discipline (Film / Lit Criticism) to get anything out of it.
That said, I do have such an interest, and I found the book to be informative and engaging. Kudos to Dr. Mogen for keeping the tone readable; academic work is frequently extremely dry and full of jargon, which I can read, but it makes the going slower. Dr. Mogen keeps this piece largely free of words that I'd have to look up in my Literary Theory Lexicon.
If there is a downside to Wilderness Visions, it would be that it is a high level overview. Dr. Mogen admits to such in the work, and I don't find this to be disappointing, but the book is, on the other hand, only a starting point.
A word of warning: there is another work on a very similar theme, Space and Beyond. Avoid it. It is an anthology in which more than half of the book has nothing to do with the topic, and it is very expensive.
