Completely worth watching for now! I've only watched until episode 3 for now, but it's good to see something different on tv... Even if you have other shows that deals with revenge (Nikita by example), it's quite different, because they really don't try to make people think what she does is a good thing (whereas in the other shows, revenge tends to be praised...)
Anyway, it looks like a lot of things can happen, and I like the casting!
She looks beautiful in the series, except for this last golden outfit that I really think is awful... They could have chosen something way better!
