I personally think that this was a pretty adult kids film too :D They showed the horrors of the war, and by giving the Clone troopers distinctive personalities it made me care more about them and when they're watching their comrades die in battle, it actually made me feel this was more than just disposable chars fighting more disposable chars.

And the kids thing adds to the FUN too! Space battles, a story that is tight and doesn't go off into weird tangents, heroic feats, good guys being good, bad guys being bad, and awesome lightsabre battles that have feeling behind them :D
