Since this is bumped, I have to say that I really loved this game, voice acting aside. It's a shame that a lot of people haven't tried it just because of its voice acting or because it looks/seems blasé at the beginning, but it gets better.
The Harada/Mitsuda/Tsuchiya OST was fantastic, the story had lots of twists and turns, the weapon system was so fun to toy around with, the battle system was fantastic... I just couldn't wait to play it when the weekend rolled around.
Definitely one of the bigger hidden gems on Wii, imo.
Edit: I just noticed that I posted twice on the same page pretty much saying the same thing in each post. lol, clearly I need sleep. Doesn't matter; the game deserves lots of love. The battle system, I felt, had a lot of depth for what it was, imo. I couldn't stop gushing about it to my friends after I finished it, and the postgame content (the extra bosses and dungeon were nice treats).
I also think you should have been able to see the costumes in battle/on the field, though. Some of them are really well-designed, so it's disappointing that you couldn't see them in their full splendor.
