I tuned in to the first episode of Reign, and couldn’t watch anymore. The “costumes” looked like leftover Prom dresses on the super extra clearance discount rack. No way I could get past that.
Agree about Musketeers. I enjoy the contrasts between the dirty and gritty soldiers and the elaborate court dress.
I thought The Borgias and The Tudors did a fine job. I must admit I don’t know enough to pick at details or historical inaccuracies, but they were visually appealing to me.
