I will keep this short and sweet--
The series is just how I remember it, engaging, fun and a whole heap of facts and trivia. It was thoroughly enjoyable and entertaining for both my students and my friends. IT IS WELL WORTH THE $11.49!!
The only downside is the DVD quality: Its a little below average, but for twelve bucks I wouldn't complain.
(If you do watch the series for nostalgic reasons with friends, try this drinking game: Whenever Zack screams "IIIVVVVYYYYYYY" while falling; take a drink.)
Full series (all 40 episodes)
Educational without being blatantly educational
DVD Quality is low
DVD Packaging is terrible (Paper Sleeves inside a DVD case)
