You'll rarely hear me complain about a film, especially an umpteenth followup in an apparently endless franchise, being too modestly scaled or too short. However, in the case of this latest installment in the KKU, I do feel obligated to ask: Really? This is it? This whole, paltry, badly shot thing exists simply to get Jackie Chan and Ralph Macchio on-screen together – and even then only barely, and not until almost a full hour has passed?
