Query: Why would you buy this book?

Even though I had this book given to me, I still couldn't justify what I spent on it (a little time). Maltin has to be the worst, in what is clearly marginally useful profession. I mean, if you're reading this, you can simply go on the internet and find all sorts of better, more custom suited, reviews and suggestions. Give this one a pass.
