District 9 was outstanding, I thought the last Star Trek film was fantastic (barring one really irritating plot hole), Iron Man, Cloverfield, Sunshine... all good.

I don't agree with you that all science fiction requires ethics and morality, and not much in the way of action. Perhaps you could say that there is a subset of the science fiction genre which requires that, but science fiction is more than that.

I'd say Star Wars is still very much sci-fi... sure there are elements of fantasy, but as a whole it's very much a plausible sci-fi movie. And there's numerous internal conflicts, they just spill out into action, but I think this happens in a very sizable number of sci-fi movies.
