Dialogues seemed to be written by an amateur writer. We don't need to listen to a running inner commentary, that's annoying, it's not a book. Swearing is out of character, for a girl who's lived all her life in a foreign orphanage, with no access to infrastructure or internet for that matter, as clearly shown in the fist episode. Also, every foreigner conveniently knows English.
Said that Cinematography, plot, direction, action and VFX are bearable for the budget it's seemed to be made in.
