I want to see the next episode!
I do not care if the "revenge" plot has been done before, b/c "person A getting revenge because of what person B has done" has been happening for millennia. It's what you do with the plot to bring the characters to life that matters. I think animation can almost always be improved upon, but the dialogue was crisp and to the point, letting the action do the work. I enjoyed it and way to leave us wondering what will happen next!
