Too much of it is an amalgamation of worn-out story (that is not very funny); that said, the stunt sequences are as wild as ever: plenty of huge-scale stages and satisfying destruction. Incredible that Jackie Chan's middling work can still be enjoyable.
Rewatching this last night, it almost seems like a very tired remake of "Police Story 4." Thankfully, Jackie Chan going through the motions is still pretty entertaining. The final stunt sequence featuring a truck going off a bridge is pretty amazing stuff.
