RE: S&P restrictions
Don't know if anybody else has seen this, but in the book Batman Animated by Paul Dini and Chip Kidd they printed a sketch, done I'm guessing by one of the animators, showcasing everything they were prohibited from putting in the show (children in direct peril, drug abuse, nudity, etc) all in one image. It was pretty over the top and hilarious. I don't own the book now, but plan on ordering it.

RE: Heart of Ice
One thing that didn't come up in the review was the quality of Michael Ansara's voice acting as Victor Fries. He somehow manages to make Mr. Freeze sound almost robotically cold, yet still expressing great emotion, mostly anger and sadness. Added to this was the processing that made him sound even more distant and cut off from the rest of humanity.
Good stuff kids.
