Unusually for me, I drafted a long post regarding this but lost it when my net connection failed - and I don't have any plastic toy wizards (or smurfs) in the house!
In summary, I agree with the comments above about this horrific propaganda, designed IMHO to control the parents as much as the child. I could envision this household as being the setting for domestic abuse as well.
Cedars: great job! More power to your elbow.
A thought strikes me, inspired by Think's comment at the top of this page. From what I observe in the UK at present there seems to be quite a movement in education circles to enlighten teachers as to parental, home, cultural and other influences on children which may affect their learning capabilities. Just an idea, but might it be worth making the relevant authorities aware of this DVD? I'd suggest sending it to Michael Gove (UK Minister for Education). I'm happy to do it if you wish, and I could also forward it to my local MP with whom I have a connection.
