I didn't mean to sound so harsh. My point was that perhaps instead of fighting the art teacher you could work together and help your ds complete the assigned work.

I appears to me she has some valid points. Your son is very lucky to have you and your husband and I am sure with your help he will catch up. However, I think he needs to hear from you that althought is is great he is having a great time making movies and he can continue to do so in his spare time, it is important to also do the assigned work at school.
