I picked up this book with the idea of getting just what it says out of it... the information one might get in any CRASH COURSE. Well, Lo And Behold, that is exactly what I got. The basics were explained, and lots of 'not within the scope of this book' caveats were given. I have since picked up a couple more books on advanced Flash techniques, and FS. I would venture to say that the negative reviews this book has been given were due to the facts that ONE - the reviewers did not take the 10 seconds to read the intent of the book - and TWO - because, in all likelihood, the reviewers were too ignorant to comprehend what the book was attempting to teach them.
