Both
Trouble Man and
Coffy come highly recommended as does
Hit Man based on what i've seen of it. Where's the official DVD release of the latter title, eh?
However,
The Human Tornado and
Dolemite never really did it for me despite having the odd amusing moment here and there.
Nothing personal against the late Rudy Ray Moore but imo Blaxploitation's best badasses remain Fred 'The Hammer' Williamson and Jim Brown. Class acts both these guys.
