Where are you getting "violence and graphic mayhem" from? The description is
, "The drama from Universal Cable Productions is set in a postwar era in which a newly formed Unity Democracy orders a volatile mix of humans and trans-humans to lead the Starship Defender on an expedition in search of lost worlds requiring law and order." That doesn't suggest excessive violence to me, just some degree of anarchy.
I'm not sure it's necessarily a "cop show" either. If anything, it sounds kind of like what Andromeda
might've been under Robert's guidance after the Commonwealth was restored -- a show about a starship bringing civilization to a post-collapse frontier. And I'd imagine that's not just about arresting bad guys, it's about helping the local worlds set up their own legal and judicial systems, like the way US forces in Iraq guided the Iraqis toward self-sufficiency.
