The too modern clothes thing I dont get. Its an entirely different world where people can do magic. I remember the only episode ive seen of Big Bang theory had the Sheldon character mad about the renaissance festival having inappropriate for the era clothing and corn dogs. The other characters convinced him to dress as Spock and pretend its an alternate world to explore. He was able to enjoy it then. I think folks could enjoy thing smore if they dont expect things to be exact copies of things they are not exact copies of.
