I honestly don't understand what people's problems are with this movie! The characters are interesting and memorable, it's got a good, is somewhat predictable story, the action is good, and it has a great story of what happens when you ignore the value of human life and lose respect for the past.
People say it's bad because there's violence, we'll, there's violence going on everywhere, in movies and in real life.
Yeah, one of the characters is a chain smoker, but a third of the population smokes anyway, and adults are bigger role models then cartoon characters.
The action is superb and I love every second of this film. If you're into the action genre and want a movie to introduce your child to genre as well, this is the best movie for it.
