Anime for Kids

So my kids, particularly Matthew, love Anime movies. They haven't seen very many, but they've really enjoyed classics like Princess Mononoke, Spirited Away, Kiki's Delivery Service, and My Neighbor Totoro.

At GenCon last week there were a number of Anime DVD vendors present, but I never got a chance to talk to someone about recommendations for kids. Any help out there? Are there good sites out there that provide reviews and content recommendations for Anime? Any recommendations of specific titles?
