Yes, THAT John Grace.
An R-rated knockoff of MR. MAJESTYK, has a fairly ho hum buildup until the incredible final 40 minutes that present the best vigilante mayhem of the 70s. My rating may likely increase if I view a better print. This was a murky, short lived upload, sourced from a VHS dupe that was on Youtube for a week until those mutant brothers sent a cease and desist. Can't say the myth around it is really deserved, as scarcity breeds hype, but I can see why those who caught it back in the day never forgot it.
