Great points Curt.  And I agree, in fact I had said in one of the earlier posts that if done well they will both inform and entertain me.  I guess with me it's just a matter of making things black and white or prioritizing them.  When I go into a film/documentary and the reason I am wanting to see it is for educational purposes, then that is the way I concentrate on keeping it while I'm watching it.  Afterwards, when I have time to reflect on what I've seen I can go back at a later time and watch it a second time for nothing but enjoyment if I want.  But more times than not, I try to keep the two seperate.  That's just the way I've always done it.
