Tarm: That's because they don't want anyone to think that they didn't understand the show.
Coelocanth: Lost is actually what pops into my head right away. I saw the first couple episodes when it first aired, thought it was stupid, and never bothered with it again. I don't think I'd say I didn't understand it. I just didn't like it.
Elmofongo: Don't forget swear words like fuck and bitch and cunt. Swear words in a medieval fantasy setting, unacceptable for me.
Coelocanth: There's actually a good reason for that. If they used the period-accurate swearing, it would sound so anachronistic to our ears (and some would sound outright ridiculous) that it would be even worse than using the modern terms. Sometimes complete accuracy detracts from the production and swearing is one instance where this generally is the case when the setting is medieval or based on medieval times.
I just don't want swear words at all in a medieval setting, fatansy or historical, with very few exceptions like Damn, Hell, Bastard, and
mabye shit (emphasis on Mabye) it just sounds wrong hearing Knights, Princess, Kings, and Queens saying swear words like fuck. Probably because I expect them to be more classy than that.
