Right, it sounds like an episode, but not like the rest of the movies. And my goal was to avoid the pretentiousness, which "Thy" will just bring more of. And there's already a Motion Picture edit called "Phase II: In Thy Image" and even a Star Trek V edit called "Phase 2: In Thy Image". In fact, they are the only two Star Trek movie edits on Fanedit.org besides Kirkless Generations! LOL
From FF's list, "The Human Adventure" could work. I've never really understood the tagline, but it might fit. "The Continuing Voyage" isn't bad as it is descriptive and even a little spoilery as V'ger could be the voyager. We do already have a movie with "Voyage" in the title, but I still kind of like it.
I still like my idea though. ;-) I'll try to mock up a title on the way home. Plenty of flight time.
