What a horrible introduction to such a great programming language. I lost all motivation to learn anything about ActionScript after trying to stay awake for a couple of hours. Not good for those using Flash for artistic purposes. Maybe good for programmers who just need a reference. I've had good teachers, and bad teachers. This one puts you in a coma due to a lack any type of human emotion or social skills. If you have spent your life in front of a computer, not communicating with anyone other than your 10th level paladin/wizard and his cohort of wood nymphs, this book is for you!
