I like the title. Could mean anything.
And I think the words of the Bard were used only once in a ST film title, so calling upon remembrance of same seems a bit trite.
...that being "The Undiscovered Country". At first, it was for The Wrath of Khan, but it was thought to be too cerebral and not catchy enough for the 80's crowd. Then it was reused for the sixth film. Fitting.
Yes, I know there were some Bard'ish titles in the original series, and in other ST shows, but I'm thinking in terms strictly of the movies.
