Rocky Balboa is probably more towards adults, but even though when I went into the theater and saw only adults, is was completely appropriate. With Sylvester Stallone coming back from Soy Kids 3-D, kids will recognize him. It's pretty much only the language throughout and the bloody, but brief boxing violence between Balboa and Dixon. If your kids are crying after the movie, during the credits they show people trying to climb the steps that Rocky Balboa tried to climb; some of them funny. It was a great movie, totally underestimated, and a great use of your money and your time.
Even though Rocky Balboa is a story about passion and going for your dreams, it wasn't a very bright movie. The whole screen just seems dark in every scene.
This movie is a must see for all boxing fans. It has a ton of action throughout the entire movie. I agree that mostly adults will like this movie, but that doesn't mean that kids won't like it. I loved it.
