I like the father figure in COP. He is a complete character that you get to "know" throughout the ride. Plus, he was one of my earliest impressions of the extents to which Disney would go for "realism" at the time. Very cool (and his little dog, too!)
And speaking of "and (your) little dog, too," I do think that the Wicked Witch is cool in GMR. Movements are well-done. Unfortunately, they put all of the pizzazz in her, it seems, and absolutely none in Sigourney Weaver ("Aliens" movie sequence) or the Busbee Berkeley opening sequence. The Busbee Berkeley thing is a horrible, plastic way to open what could have been a great ride (don't attack me, please, GMR fans: I just think it was halfhearted in some places).
