Predictable? Yes. Entertaining? Also, yes. Donnie Yen's charisma saved what would otherwise have been a standard teacher saves students in trouble story.

Donnie Yen's character, Henry Chen, returned to teach at his old school after serving in the United States military. He was assigned to the worst class in the school. What he found were standard movie fare students---poor students, students with parental problems, misunderstood kids, racism, kids running errands for gangsters, stressed kids, kids with unfulfilled dreams. Chen studied their histories and then stepped in to make things right by unconventional means.

In addition to the teenagers' problems, the school was in danger of being shut down because of underachieving students. Throw in gangsters who intended to develop the area where the school sat, and you've got all you need for conflict. Add in a couple of awesome fights when the plot slowed down or became too serious to keep the audience invested and you've got a winner-it's Donnie Yen, we don't expect him to solve all of his problems in a peaceful way, do we?

Donnie elevated a familiar and at times clichéd story with his star power. He transitioned over to less action and more acting smoothly in this film. The kids were likeable even when doing unlikeable things. One problem with such a large cast, the villains were underdeveloped even though one had a key connection to Chen.

This movie was a combination of social concerns and martial arts displayed in a fairly balanced manner. Some problems may have been solved too easily, but sometimes we need to believe that children can be saved from others and themselves and that someone cares enough to risk stepping in to help them. Big Brother had moments of inspiration and enough action and character development to keep it entertaining. Donnie Yen as Henry Chen didn't just save the children in this story, he saved this movie as well.
