Jackie lived his experiences. This author is, to the best of my knowledge, basically just some guy with a website byline. (Presumably he's had some sort of hardships in life, because nobody escapes unscathed, but I doubt they compare to Jackie's.) I'm not sure the author has all that much moral standing or skin in the game to make me care much about his opinion of Jackie Chan's life.

He's welcome to it. I just don't see it as anywhere near as interesting.
