My Dad watched the World at War series back in the 70's when it came out and I always watched it with him. It was highly impressive tv. I don't think kids today have very much emotional depth because the echoes of war are kept off television for the most part. If anything, they think war is fun. World at War was earthshaking as a documentary series- you can't see something like that on a daily basis and not be changed forever by it.
