Metacritic reviews

When he finally takes the screen for a prolonged routine, Lee reminds you that he was indeed a thing of beauty in motion. However, if it's the missing Lee footage you've come for, there's no reason to catch the first hour or so of the film [26 May 1979, p.C9]

There’s no reason whatsoever to watch the entire thing; just skip to the end, which features a series of bone-crunching fight sequences that suggest Lee was just getting warmed up when he left.

The film's inconsistencies, inaccuracies and disjointed editing can be explained by Lee's untimely death; the producers had to piece the movie together from the available footage. But what's the excuse for the other wretched performances? [25 May 1979, p.39]

To cash in on footage from a film Lee did not finish before his death, producer Chow puts in a double and uses out-takes for this kung-fu mess.
