It is one of Bruce Lee's best films and key to the positioning of the Golden Harvest production company in its fight against the Shaw Brothers. In this case, Bruce Lee is a talented disciple of a teacher who, having a tragic death, must investigate the subject. This film allows us to see the acting side of Bruce Lee who at certain times even looks like Jerry Lewis. It shows a bigger budget than the previous film also directed by Lo Wei and has some truly magnificent martial arts sequences. It is a film that with fifty years behind it is current and demonstrates the stellar stature of Bruce Lee. Very good.
