I put zero becuase there is no "?"
I did not watch this movie becuase it will not work. I will say a few things, however, reguarding the concept.
I think a good handful of Zelda and FF fans have thought of mixing the series. But for OoT and FF7 to be combined is impossible. Heres why:
1. FF7 is based in a world NOTHING LIKE Hyrule.
2. Zelda is based in a medieval fantasy setting, where as FF7 is a high tech modern setting. Thus, Link would see a gun and say "What the HELL is that?". Besides, even if they were in the same worlds, Link would be dead before Cloud was even born.
3. In fact, Link was NOT an adult when OoT ended. He was a boy, if you actually had beaten the game, you'd have known that. After the events of OoT he goes off in search of Navi, who'd ran off as soon as they returned to the temple of time (present). He journeyed into Terminia. After that, god only knows, but I'd like to think that there will be another game countinuing Link's quest to find the fairy, navi.
So, after looking over all those facts, we can only believe that your story could NOT have happned. Therefor, your interpritation is impossible on any logical thinking level. I started out with Zelda meets FF7 fan fictions. You've got potential. I hope you use it.
