The thing that makes Bruce Lee special, as compared to other fighters, was not his fighting.
Ya, there's that. But. He was an amazing human being that cared about other human beings. He became a symbol of erasing racial barriers. He said screw you to the old kung fu masters and taught literally anyone who wanted to learn kung fu. His best friend was Japanese at a time where hostilities between the China and Japan were especially intense. He always included different ethnicities in his movies. His 'Enter The Dragon' had a European American hero, an African American hero, and himself as a protagonist.
He was a man of PEACE and a philosopher. In his movie, he says his style of fighting is "fighting without fighting", as he then proceeds to trick a bully into getting stranded in a boat. He quoted Buddhist monks saying, "The truth is like a finger pointing to the moon. Stare at the finger and you'll miss all the heavenly glory." He is the finger. He became the first truly international movie star, no Hollywood movie ever featured a "foreigner" as the main star before.
When he got hurt, he wrote a book about fighting and philosophy. His philosophy on life, be like water and flow. He referred to what he does as ART. Martial Art. His interest was in self-expression.
His greatest asset was not his fighting. It was humanity, his heart and mind .
"Do you still think of yourself as Chinese, or do you think of yourself as an American?"
"Do you know what I want to think of myself? As a human being, because... under the sky, under the heaven man, there's but one family. It just so happens man, that people are different."
