I had low expectations going in because the advertising campaign was so poor, but I ended up finding that it wasn't as bad as I anticipated. This is largely thanks to Ben Wang’s spirited and charming performance as the young “Li Fong,” who has just moved from Beijing to Los Angeles with his mother, a doctor (Ming-Na Wen), following a family loss that is explored further on. He connects with the pizza restaurant owners, "Victor" (Joshua Jackson) and his daughter, "Mia" (Sadie Stanley), but quickly learns that Victor owes money to some dangerous people and wants to fight his way out of debt. Recognizing Li Fong’s aptitude for kung-fu, they decide to join forces, leading to a series of adventures where the newcomer faces off against local champion “Conor” (Aramis Knight). To prepare him, he receives guidance from his Chinese instructor "Shifu" (Jackie Chan), who secures help from none other than the original “Karate Kid” (Ralph Macchio) so that Li Fong can learn the philosophical martial arts techniques of the "Miyagi" style. It's a familiar story, and Macchio’s acting feels stiff—like one of his former teacher’s bonsai trees—but Chan brings some lightheartedness to the film, and there's just enough action to prevent it from becoming overly sentimental. You might not remember it thirty minutes after watching, but it is probably only surpassed by the original 1984 movie and provides a pleasant way to spend a couple of hours.
