I'm not sure what there is to hate about a female highwayman. Premise sounds interesting. Hopefully it goes on long enough to produce a proper USB scene.
I really don't think the language is a problem. Seems like not worth getting angry about.
Anyway hopefully the show produces something else. Lot of potential for clothing theft in a show about a female highwayman. Especially if she needs to disguise herself to escape the authorities.
In episode 6, we see Nell's sister wearing the stolen dress. (Can't find a clip for that one.) The episode is told from Polly's perspective, as she develops a crush on the woman who mugged her.
