Instead the songs are just background. The movie is rated PG and this is probably the biggest difference between the studios. This one isn't aimed exclusively at the kids. One character, Chel, acts as a love interest for our heroes. She slinks and jiggles about the screen in a way you don't see in Disney movies.
Characters can actually bleed and animals can be killed.
There is also a monster in the film that will undoubtedly cause a few younger kids to scream. These are all bonus points in my book but if you have kids it's something to consider. My biggest regret is that Cortez wasn't used more. I loved the way the character was drawn and voiced. He had a huge physical presence and a menacing glare.
