"The smirk" definitely wasn't Katie's or Nathaniel's idea. I don't think they would ever overdo it at something like this, since it only makes the characters dislikable. I think that it was an attempt to make the characters seem more evil and simplistic and less complicated. It must've been the ida of the producers in both cases. I also have to agree that Katie did a perfect job in portraying Morgana and must have worked hard, since her character evolves more than anyone else in every season. However, this must have easily been her best season.
