What would happen to the rating of the first movie, if it had different actors/actresses? Would it still hold its charm?

I'm sure it would stay the same. Balto's voice is awesome, but i still don't like him lol

To be honest, it doesn't really mean much to me who plays the characters. It's the characters in person I look at, but I guess their voices also have to suit their personality. And I couldn't see their voices being any different to how they were in the movie.
