F4 is a composite, with two Taiwan-born-and-bred members, one who lived in Singapore for quite some time, and one Chinese-American. They look sharp, and have a somewhat foreign feel. When you combine these features with their packaging in an "idol drama serial," you've duplicated the product formula blown in on the wind of Japanese idol TV shows.
新近的 F4 則為混合風格，成員有土生土長的，也有 ABC，外表亮麗、作風洋派，加上偶像劇的包裝模式，是日本偶像劇風潮吹拂下的最新「產品」。
