I certainly didn't watch Hunter for the stories: they were fairly predictable. In particular, Fred Dryer's "Hunter" was somewhat comedic in the way he would nail the bad guy in a macho way with one or two perfectly placed shots. I also felt his acting was somewhat wooden and prone to macho posturing. You could really see this get worse as he took more control of the series. Anyone who knows anything about the police would suspect that if ex-Vietnam vet Hunter really offed as many guys as that, he'd had a lot of explaining to do. On the positive side, the character itself was somewhat sympathetic because he wasn't stupid.
I found Stepfanie Kramer's acting to be much more natural and have a greater range (eg. serious to humorous), and wow, she was great to look at (I was in my mid-twenties when this show was on the air). She was cast as the sidekick, but to me was really the star of the show and the only reason to watch it. She's got a singing career now, but it would be nice to see her get a really good movie role. It's probably somewhat unlikely now, given that Hollywood doesn't favor women over 40.
