Are you considering homeschooling your child with movies? That really is not all that bad of an idea. I would not however make this a full time teaching/learning idea. Periodically there is nothing wrong with using movies. Now there is a difference in using teaching videos in homeschools and movies. Please do not mistake them. I am all for using the teaching videos as it is easier in most cases on various lessons. Its the movies ya want to be careful with.
That being said, check out this site for your movie helps.
