Second best Villain of all times.
Over on JoiIto
they were talking about the use of stereotypes in movies. Some people thought it was a global conspiracy. Really, its all about economy. Showing someone recognizable as the bad guy lets you get on to the rest of the movie that much sooner, and keep the film that much shorter. (Movie theater owners like short films--more screenings per day.)
On the other hand, once in a while someone turns conventional wisdom on its head and does the exact opposite, like in Beauty and the Beast, with the antagonist Gaston. He was a great villain and it makes the whole movie richer.
