Really not feeling Inara
I feel like the concept of the character (and her stunning wardrobe) was genius, but Morena's such a blank actress that she just couldn't sell it. What makes it worse is the total lack of romantic chemistry between her and Nathan, making the love plot REALLY onerous.
To me, she's the one casting mishap. Had the show continued, she would have to be written out. There're only so many close-ups of her blank expression one can take!
