Knowing where the story goes from here i think it really does a better job of showing the gradual take over and corruption of Cloud's mind. The original game tried it sort, but ultimately Cloud just gives into Sephiroth's will during the temple of the ancients and crater sections of the game. Rebirth does a better job of showing the influence taking him over as they get closer to what is actually Sephiroth's goals.While I'm lukewarm at best with the multiverse plot I do like Cloud's development. Or degradation really. We seem to be in uncharted territory with him after the ending
The real question I have is whether they'll give Sephiroth a big revelation or if they'll lean more into Jenova as the true enemy here. Sephiroth is functionally an avatar of Jenova and she's the real villain here, it's never really been about him.
