Adhering closely to the original 1984 'Karate Kid' blueprint that made Ralph
Macchio and Pat Morita household names, this Will Smith-produced remake ups the stakes by moving the action to China. Casting Jackie Chan as Mr. Han, a martial-arts master who teaches his young protégé (Jaden Smith) how to fight, lends an air of authenticity to the otherwise by-the-book narrative. Grade: C-plus.
