I'm not a Seinfeld fanatic pero pinatos ko rin 'to. hahahahaha
I must agree, it's a kid movie. End of discussion.
Comparing the moral(s) of the movie with Happy Feet (you know... how things are related, blah blah blah, social responsibility, food chain, ecosystem etc.), the latter is better. The Bee Movie's manner of sharing the lesson was very comical and in a creative and humorous manner, probably, making it more appealing to children than but not as compelling for adults.
