I like it for one simple reason. It looks like it focuses on the characters, not on OMG FALCLIE MELODRAMA RAGNAORPHANCRADLEPRAETORIUS MANAVIN GOD REBIRTH WORLD LIGHTINGIUNGU.
Seriously, though. Think about how much humanity has been missing from FF casts in the XIII titles. The concept render for this game has them GRILLING, ffs. That's something people do. If nothing else, realize that this game has a tone and a thematic and is now actually FOCUSED on something. I couldn't be happier with that trailer. Also, look at early-game KH2 combat compared to late-game. It's like night and day, and I'd be shocked if this weren't similar.
