I really love opening with “A golden age is ending.” It perfectly sums up the entire tone and background noise of the trilogy right from the start in a very evocative way; it puts all the events that follow into a much more interesting context. Succinct, evocative, poetry.
I also personally like ending with the Jedi restoring peace to Amidala’s “kingdom,” because I like the fairy-tale evocation, though I agree there are good reasons to go with other third paragraphs.
