Call it corny, call it whatever you will. Say the same thing about the movie. Personally I thought the movie and the score were well made, much more than what can be said about the absolute trash that is usually shovelled out by Hollywood. This is a movie that whole family can enjoy (cliche' coming in for you sir!). It has little language, little violence (though a few intense scenes unquestionably) and great humor all-around.
The score was perfectly matched to the film. I continue to enjoy it today, even as a 28 year old (ouch) guy.
