Don't pay any attention to showrunners, just watch the shows, any shows.
In fact I don't know of any other shows that pay much attention to their "runners" besides ones that were created and run by the same guy, i.e. X-Files, Breaking Bad, etc. Even then they weren't that mainstream compared to the actual show.
There was Gene Roddenberry, creator of Star Trek, but after he died nobody paid much attention to the showrunners.
