SNSD is actually very appealing

So with regard to the K-pop girl band SNSD (Girl's Generation), I like them, their songs are so catchy!
I just don't get why everyone is like, 'So and so is not a good dancer, I like this one better, and so and so doesn't look Korean, or so and so is American'. I think they are all cute and different and I like all of them, but that is based purely off the music videos. I haven't read anything much about them or watched any tv shows that they were on or whatever.
I suppose if I have a favourite it would be based on looks only since at least one of them has had her voice auto-tuned (in Gee at least), and since to me they all seem to dance equally well.
I guessssssssss my favourite in terms of look and not much else, I like both Yuri and Tiffany...and maybe Sunny. But only a tiny bit more than the rest. It's really no stress to pick because they are all great. And just to set the record straight, who cares if someone doesn't 'look Korean'... she adds to the overall appeal of the group. It's so strange, because people wouldn't say that here, about a singer or entertainer, we wouldn't say, 'She or he doesn't look like they are from NZ.' That is irrelevant... I don't understand why it's an issue. And same with being or looking American. Who cares... anyway it would make the band have more depth of appeal, like I said. Well, I think I still like the video for 'Oh!' best, but the tune of 'Gee' best so far, then 'Run Devil Run'. Not impressed by 'Hoot'.
I am addicted to this band now... ah well why fight it? I want to hear the English version of 'Gee'... is it real? Does it exist? I must find out.
