I used this program for my science class. My students loved it! They learned some interesting facts, saw damage from earthquakes we talked about in class and never once did I hear that it was boring! Can't beat that!
Positive

It was interesting to read The Foxes of Harrow again, as a "senior citizen, since I was only in my early teens the first time I read...and enjoyed...the book. It is quite sensual, considering the year it was written. It has held up fine during the years. I probably understood the nuances better as an adult than as a teenager. Frank Yerby was a brilliant writer, and in this book he presents a balanced view of what white slave owners and their slaves faced during that pre-civil war era. I couldn't help comparing it with Gone With the Wind as I read it.
Positive

Like other reviewers I also grew up watching A Charlie Brown Christmas when CBS showed it every December and I liked every minute of it including the heartwarming speech by Linus about the true meaning of Christmas and I think this is a great Christmas cartoon but I was disappointed with the extra feature cartoon It's Christmas Time Again Charlie Brown because It was very uneven and choppy!
