I saw Mulan, Anastasia and Prince of Egypt in a row. I loved Mulan, I loved Anastasia even more, and now... Well, I must say that Prince of Egypt is probably the best of all. I'd even say, the best animation feature ever produced in the USA (aside from Batman : Mask of the Phantasm).
It is a real piece of art, aiming to entertain everybody, not only act as a baby-sitter movie for kids. There aren't even any pets here. Only a great story, moving scenes, credible characters and fantastic music and storyboard. You will love this one.
