The casual fan knows the Vulcan hand thing, Captain Kirk and Mr. (or Dr.) Spock, and the Klingons. That's it. The casual fan wants a popcorn flick. I would like to see Star Trek do something unique, to try something that isn't so safe. And doing a movie where a Khan-like villain threatens the universe, the Federation, Earth, or the Starship Enterprise
, is boring. I don't want another villain with Khan's screen time. I want something fresh, but whenever the deviate from that, it's killed by this generation of fans. See the thread about Insurrection being "small potatoes, the stakes weren't high enough" in the other forum.
