I don't mean to offend anyone with this, just thinking: why is it so that all of you who love Yuna so much are saying to Lain that "you have your opinions BUT Yuna's so cool why don't you give her a chance?" (maybe not exactly that but you get the point) when there's no chance she'll change her mind, moreover she's not trying to change your minds about loving Yuna? Oh well... you must have your reasons.

I personally didn't like Yuna's appearance in FFX, however it was a little better in FFX-2. To my mind, she's not even in the top 10 of female FF characters. Why? Because to me, she just looks a little too immature, even with all you've said about losing her father and all that stuff. I hated the voice - and not only for that slow way of speech (which I don't think was all due to lip sync, 'cause none of the other characters had anything like that going on, did they?), but also because I didn't like the tone of the actress' voice (and remember folks, that's just my opinion!)
I hated her dress - still do. In that she looks like she's a bit plump and has a too big backside.. you know, and I didn't like those gummi-boots either. But that's not a reason to dislike her, now is it :P
But I do dislike her, even if it is because of reasons I don't know myself. So you have got one soulmate here ;) and at one Finnish forum where I go to, many people dislike Yuna (whereas the whole game, but who cares xD), too. So you're not alone, Lain :o!
