I highly doubt Benedict Cumberbatch's Khan is going to be quoted by someone like Quentin Tarantino in twenty years.
I see nothing iconic or standing out in STD. Major points in the film are just rehashed from the previous film (Enterprise rising out of the clouds, the space jump, Kirk's promotion/demotion thing, etc...), and the emotional climax of the film is taken from TWOK, just with reversed roles. Cumberbatch just chews on his dialogue like it was a Lion chocolate bar, but if you take that away, it's just really shallow talk. Some characters, like Carol Marcus, are just in there for fan service but serve no real purpose. The film wouldn't lose anything if you removed her character from the script.
The only memorable thing is the Enterprise rising out of the water. And that's just a cool visual effects shot for the sake of it, but there was no meaning behind it.
