The ninjas are not particularly secretive and the Tiger (bad guy for the film) barely breaks into a growl let alone a roar. Other than that this is a reasonable kung-fu flick.
Comical highlights for me include two men not realising that the person they are travelling with is a girl, an obvious transvestite fighter and a man tickled into submission. This is a Godfrey Ho production but this one is blatantly played for laughs.
Fights are slow paced, robotic affairs but that adds a level of charm for me. Dubbing is at times atrocious.
Worth a watch I suppose.
