Titles are as much about promotion as they are about reflecting story content (and sometimes more so -- Nick Charles was not The Thin Man
, and the later Pink Panther
movies had nothing to do with the Pink Panther diamond). So I figure the meaning of The Voyage Home
was largely to promote the idea to audiences that the movie would be taking the characters, not to some strange new world, but to a recognizable Earth, to our
home. Yes, nominally it referred to the voyage back to Earth to deal with the consequences of their actions, but that was secondary, I think.
And yes, I think it's also reflecting the idea of the restoration of the status quo, getting the Enterprise
and their old posts back.
