The 1968 movie by the director of 'The Flying Guillotine', Ho Meng Hua, is a little disappointing actually. Ok it is a late 1960s sword play formula movie (so you know what to expect), but I feel it still lacked a little, even for that genre. Not much was made of the killer darts really, so I saw it as just another SB sword play film. There were plenty of other evil weapons in use by the bad guys (including mini-cymbals), but again even those didn't lift this movie. It is an enjoyable 80 odd minutes, but nothing really special and certainly not out of the ordinary.
If I can offer one comment in its defence, there are plenty worse movies out there, hmmm I guess that doesn't say an awful lot, 5/10.
