This is open-mouth comedy, where subtlety don't belong. And there's a fair whack of toilet humour, quite literally. I found much of the first half more irritating than funny, though the second half was reasonably good farce.
Reviewer Score: 6
Loads of fairly good special effects. I particularly liked the words of the buddha chant which circled the demon near the end. Of course, the two female Man's (Cheung and Chik King) are a joy to behold, whilst Billy Lau works harder than anyone else for laughs.
Overall : Annoyingly uneven, but the good bits eventually outweigh the trash.
