Ronny Cox had a tough job to fill. He had to convince us he was a capable commander with a different style, and whose actions can be seen as plausible, yet he still has to be the bad guy on the ship. I'm glad he had success with villains; when he was playing good guys, like in Deliverance
or his own TV series "Apple's Way", he was often unmemorable. Except when playing his guitar with a kid on a banjo.
