Story is too juvenile
Big Brother is a classic story of a bunch of delinquent high school students being tamed by a new teacher in this case Donnie Yen. He teaches them about life and they come to love him. Yen gets to give monologues about the inequality of the Hong Kong school system. Here’s the thing though. The students are facing real problems. One deals with racism. Another has a father that doesn’t care about her because she’s a girl. Another lost his mother and then his dad became an alcoholic. Yen shows up with a smile and just believes that his positive attitude will change things. It’s a story meant for 13 year olds.
