The title also fits the "story" within the subtitles themselves:
The Phantom Menace: there's some hidden evil (the Sith)
Attack of the Clones: the Sith make their move (the start of the Clone Wars)
Revenge of the Sith: the Sith claim their victory
A New Hope: a new chance to defeat the Sith despite their victory
The Empire Strikes Back: the Sith get the upper hand again, despite the "new hope"
Return of the Jedi: the Jedi finally defeat the Sith
The Force Awakens: with the dark side extinguished again, The Force can "awaken" and breathe again
Even if that's not what happens in the film, I like that the new subtitle continues the little summaries/stories that can be surmised from the others.
