This film from the early 1970s stars Ivy Ling Po, it seems to have a bit of many genres in it. I found it a little disappointing, like this film didn't know what it wanted to be, wu xia, kung fu, horror, zombie (non-hopping variety) or a mystery film.
Overall I got the sense it was just a little too silly, and it kept changing the direction it wanted to develop, thus I felt a little disappointed with it.It isn't a bad film, but just not as good as the potential it would have had when it was an original idea.
It is worth a viewing but it is far from a classic and you may well end up scratching your head (like I did) at the end trying to figure it out. Maybe it is better to just sit back and enjoy Ivy's performance.
