I've heard about this and I'm not too impressed with the cast.
I definitely didn't picture Ariel Lin as Kyouko, not that I don't like her. I do. I think she's a good actress and can be very pretty, but I just don't see her as Kyouko.
If I had to pick a Taiwanese actress to play Kyouko, I was thinking more along the lines of Rainie Yang or maybe even Angela Zhang.
As for Jerry Yan as Ren, I just can't see it happening. He was alright in Meteor Garden playing the bad boy, but as Ren? I don't even know which Taiwanese actor I would pick for the role of Ren...no one pops into mind. Ren is just so awesome. As much as I love Mike He, I don't see him as a Ren. Maybe Ethan Ruan?
Who knows, maybe I'll be pleasantly surprised with how the Skip Beat Taiwanese dram will turn out.
Hopefully a Japanese version and maybe even a Korean version will pop out soon.
If a Korean version comes out, I want the girl who plays Jan Di in Boys Before Flowers to play Kyouko.
