In the earliest Ferangi episodes they were portrayed as a pretty serious threat. They would go to battle and pretty much despised humans. Then they started to grow into comedy characters. By DS9 the Ferangis were kind of cariacture of what they once were and pretty much used as the focal points for comedy based episodes. What happened with the Ferangis? Did the writers decide it was better to use Romulans and newer aliens as the chief threats? Did the fans backlash against them?
