Here's why it's a great story.

Rating: 10/10 (17 June 1999)

The animation is superb. Enough said about that. The story is a fun and positive message. First: Countless ants that can all work together, yet still retain their individualism.
Second: When you put that much force to work, you can achieve monumental goals(The bird)
Third:Individuals can use a known ability they possess to overcome almost any challenge(The circus bugs do this)
Finally: There is more good in the world than evil(evil just gets more press) This is the ratio of ants to grasshoppers.
Enjoy this movie many times and realize that the positive message of it is also the reality of life.
Have a Great Day :)
P.S. It's really really funny too.
