Why are you turning this into drama, Kazemon? =| Sheesh.
Syaoran's voice is tollerable. Yuuko is fabulous and Kurogane got better once he warmed up into it around episode 5. Sakura's voice hurts my ears, and Mokona's isn't much better. I dislike Fai's the most, of all of them. Vic makes Fai sound so straight-laced, almost, which doesn't really suit him. There's so little emotion in his portrayal as well.
My only major problem with Funimation's adaptation is all the seemingly small dialogue edits that make scenes sound unnatural, or are just unnecessary. All the random grunts. Sakura's saying "I thought you were cute", in reference to her and Syaoran's first meeting, and that whole childhood scene of playing in the garden just sounded weird. Largely anything she says just sounds strange coming from "Sakura".
Some of the edits make Syaoran seem a bit less intelligent (?) as well. For example, Sakura's floating in the air in the middle of a crumbling ruin, and he says "Stay there!!". In Hanshin, after receiving the letter from Primera, "Hanshin? Where's that?" (Even though he was told where he was by this point.
That, and everytime Sakura says "Syao", I cringe. =/ But that's jut my purist talking.
Thanks for sharing, Kazemon! =D
