Truly, there is NOWHERE else but HK that a film like this could or would be made. The pace is wild and wacky, the action varies between really daft and mind-numbingly spinout. The quality of the subtitle translation is extraordinarily bad, which proves that time does not improve. There's quite a bit of joking about death (the lead characters keep reincarnating and scaring people). Oddly for a Cat IIb film, there is a little full-frontal nudity, though it's discreet. This happens when Lo (Tony Leung) sees his wish to see a prospective girlfriend naked at their first meeting come true. Unfortunately for him, it's when they are both on the critical list and about to die the meet as floating souls).
Overall, the frenetic direction-changing is sometimes less than well-done. But see it anyway. It's definitely a buzz.
