Comparing it to FFXIII, which is the only FF game I've played, I think the characters are fine. FFXIII had the J-pop dance troop thing and anorexic animie women. The games are made for JPN teenage boys, and I guess that is the kind of women they find hot and the type of dudes they think are cool. At least XIII had Sazh.
I can't say as I understand the hype though, the game looks kinda terrible. Dumbass story and and slow arpg combat.
I think the main reason I enjoyed FFXIII is because I wasn't hyped, I expected hot garbage, and it was $5 when I bought it in Jan 2014. That and the sublime music, kinda hated the music in this trailer.
