There is a very positive message, but, I will say, the movie itself, (the script) is terrible. Little kids wouldn't understand some of the jokes, which are now useless to them. And, parents will think it's all a little kid movie, and it's not really like that.
The thing about this movie, that really gets me, is the flies. Those were not-needed. They were very provokitive, and very bad-role models. The reason I don't say that about others (the mean horses), is because they were supposed to be bad.
In the end, it all turns out good, but I still think that the movie was horrible.
