Actually our kids were in public school and we took them out because the teacher was playing baseball instead of finishing the math curriculum. A couple of years later he was fired and went back to plumbing!
My husband's sisters are teachers and were a bit shocked when we home schooled but the boys and I loved it. They asked if we could start school earlier in the day so they could be finished sooner so we started at 8 a.m. instead of 9 and since we were usually finished right after lunch, otherwise known as home economics, they had the afternoon for ski lessons, golf lessons, swimming, pottery and music lessons. Somehow they did not think of those as learning, just fun.

One boy went to university and got his B. Comm. and is now a branch manager of his firm and the other went to technical school and is lead technician for a company that installs and maintains telephone systems. They are both happily married with families, living in houses they own. I'd say we did something right. On the other hand I do know a few families who IMHO made a mess of it. Kids have no reading skills, no ambition and no self-discipline leading to no future. It IS work but I would not trade those years for anything.
Regarding the movie, I've always wondered why it did not make a bigger hit. It had good acting, good plot, even good scenery...
