This is a parody.
Which means that I'm not REALLY reviewing the book, but doing the version that I'd do if I did book reviews the way I do beer reviews.
Beer reviewing (at least video beer reviewing) is based on the immediate impression, on what is going on at-the-moment. It's difficult, when recording a review, to really give an overall perspective on a beer.
Imagine if Siskel & Ebert had had to stop every ten minutes during a movie to record thoughts about the flick, and those thoughts had made up the overall review, to understand what it's like to try to do these videos.
