Balto is an a underrated treasure with memorable characters, endearing moments, howling humor, and canine villainy/heroism that rivals movies from Disney's golden-age. You'll be rooting for the literal underdog throughout while all of the supporting characters add to the charm. It's a top-tier family movie that has zero foul language and zero religious slurs, with the only near-miss being when one character says "Son of a...", leaving the phrase unfinished. If you like a good sled-dog movie, this is one of the best!
