It's true that you can tell this wasn't done by Visual Works (or they didn't use their usual procedure), but I mean, it's a promotional trailer, much like the ones made for almost every AAA game in the West.
But, oh boy, I loved it. It's a really good trailer to keep you pumped about the game. Really like the themes touched upon there and Noctis and Regis' depiction. Also, I doubt that it's too spoilery considering they, well, put it out (and beyond the beginning chapters of the game, we don't know that much).
But if you really want to avoid potential mild, possibly big... spoilers, avoid it, because who knows.
