Whenever I think about how great I thought she was as Faith compared to my "...meh" feelings on her acting here, I think it might be that Eliza isn't bad necessarily, but she's better at playing with drama and more in-your-face characters, instead of something more subdued that relies on a crapload of range instead of one specific characterization. Even when Echo's programmed to be somebody outgoing, she still has that glitchy Echo-ness that necessitates a lot of subtle tics I don't think Eliza has a hold on the way Dichen and Enver do.
