I give this 4 stars because sometimes things can be over explained to the point of boredom. While
Giobbi offers exhaustive explanations of what he has perfumed, he tends to go too far and segues too
often for my taste. Just when you think he is getting to the point, he jumps to another thought. I
often has to fast forward things that were beginning to bore me.Great theory, yes but much could be
referred to in books. Also, I hate when a magician shows 4 effects and then explains them later. I
already forgot the original trick and have to rewind to see it again. A lengthy and good lecture,
but way too "comprehensive". I almost wanted to say "get to the point already".
