The Lady and the Tramp was Disney at it's best. The only movie I can think of that beat it is The Lion King.

The music was outstanding, romantic, and amazing. So: 10/10

Animation? It's nothing like today's animation, since it was made in 1955, but when restored: 10/10

Voice Actors were at their best also. The best I can give it is: 10/10.

I'm impressed with Disney. The characters were awsome. So: 10/10

Overall: 10/10. You can't get much better than this movie. Outstanding!
