Adored by the Network: Reruns are extremely frequent, new episodes are heavily promoted, and the show was renewed for a second season after only FOUR episodes (out of twelve) were aired. It probably has to do with the fact that, next to Warehouse 13, it's the only primetime show on the network that isn't a Canadian or BBC import (all except Continuum, incidentally, having already finished).
Creator Backlash: Extremely mild case: Julie Benz often expresses in interviews how arrogant and unjustifiably overconfident she finds Amanda to be. It's more amusing to her than annoying.
"Of course Amanda thinks she can be the Lawkeeper; she thinks she can do anything!"
Enforced Method Acting: In "The Bride Wore Black," Nolan doesn't tell Tommy he knows Datak didn't commit the murder they're arresting him for or that the plan is for him to lead them to whoever framed him, so Tommy will be more convincing.
Fake American: Australian Grant Bowler and Canadian Mia Kirshner play Americans, while Scottish Tony Curran, English Jamie Murray and English Stephanie Leonidas all play aliens with American accents.
Rob Stewart probably says more in his one episode as Nolan's old war buddy than in two seasons as Roan on Nikita.
Mean Character, Nice Actor: Mean is certainly stretching it, but there's certainly a distinctness between Irisa and Stephanie Leonidas. In one behind the scenes interview, it's noted that she almost constantly worries about Kevin (the actor who plays the Sensoth in the show) because she keeps seeing the frown in the makeup and thus keeps thinking he's uphappy about something.
