^Whereas I'm deeply impressed by Stephanie Leonidas's acting talent, and I think Tony Curran and Jaime Murray are excellent too.
Yes I do see some potential in Stephanie Leonidas as Irisa. Perhaps after she gets to know her character better. Same for Curran as Daytak. I really haven't seen anything from Murray that looks out of the ordinary but I'll keep watching and will keep an open mind.
I just wonder how shows like Firefly, BSG, Doctor Who, and others, can throw 4 or 5 actors (regular and guest cast) who turn in great charismatic performances from the opening episode and others, like Defiance (and Grimm), can barely muster 2 or 3, if that many?
