Extremely good movie, probably one of the best animated movies I've seen in a long time. Could easily watch it over and over again and still enjoy it. Even as a teen i found the humour funny and the movie overall exciting.
Oh, and for people who don't like it because of things like a kid helping "DANGEROUS" animals and thinking their kid will do the same, BIG WHOOP. Its not like your kid is even going to see a salt water crocodile or a taipan and make friends with it. Also, people criticising things such as inland taipans being brown not blue. ITS A KIDS MOVIE! Get over it, seriously.
