I hate every character except Sazh or whatever his name is. You got Bubbly Bitch, Bitch Bitch, ANGST OMFG I WANNA KILL THIS KID, and Airhead Man. The two kids are my least favorite. Hope, I wish would just fucking die. Seriously. Look at the deer-in-the-headlights menu screen pic of his. How can you not one to punch the little whiny bitch? And redhead girl is so obnoxiously over the top happy go lucky I can't stand it.
The three adults are almost passable, especially Sazh, I'm hoping that more back story might make them grow on me some more. I'm starting to enjoy the battle system at least, now I know what reviewers were complaining about when they said you can't do shit in the first part of the game. Seriously, the first two hours are just spamming the X button and watching poorly written/directed cutscenes.
Oh, and I completely disagree with BocoDragon. The Japanese melodrama is what ruins these kinds of games, and I think why they've gone downhill so quickly. You can tell a good story, have it be deep and dramatic and emotional without resorting to cliché animu bullshit all the time. I'm kinda sad that this is what Final Fantasy has become, so far. I think it's improving so far, but I just had some Hope backstory so it's like 2 steps forward, 2 steps back...
