Good fighting, comical over-dubbing.
What I was most impressed w/ was the story. The complexity of the ‘spy’ aspect w/in the school was interesting to me – he kills the spies, but if the other school is mad, they admit they had spies. However, if Chen’s school doesn’t blame them, they look guilty. He forces their had.
The disguises were good, but a bit goofy, but I assume that was the intent.
The ending was a bit sudden and lacking, but that may be the style???
Bottom line, for 1972 in Hong Kong, it was good and w/ Bruce, it was even better.
