Although Showtime is a network of varied offerings, "fixers" represent a key niche. From Ray Donovan to Marty Kaan of House of Lies, these characters operate in a certain way. They're preternaturally competent men ? and sometimes the women who love them or work alongside them ? who know that with liberal application of pressure, they can break the will of other preternaturally competent men, even if their own lives are usually in desperate need of fixing.
