If you are studying WWII with your kids, or have an interest in it, or just enjoy history, we thought this was a great presentation. I would go so far as to highly recommend it. If it isn't available through your local library or other convenient rental source, Amazon offers a "view on demand" option. It was pretty long though - a couple of hours I think. And while it was primarily documenting the amazing sacrifices and courage and bravery of one relatively small, specialized group of men during WWII, it covered several battles of the war and was very informative. It was another reminder of the indebtedness we owe (and many other countries in the world as well) to the men who have fought for freedom and liberty, especially watching some of the elderly men who had flown the gliders describe their experiences.
Geoff and I watched this one:
You should watch it too, if you haven't already, no matter what you believe. It was incredibly enlightening as to the closed-mindedness of American academia. I would write more, but feel my blood pressure rising just thinking about it and think it would be best not to further elaborate at this time. I would show it to the kids at some point too, when they are a bit older.
