I was never a fan of the F4 series, I watched it just becoz everybody's going gaga over it, and becoz i had a crush on Barbie Hsue. that's probably the reason that amongst the versions, i like the Taiwanese one, though critics rated the Japanese version the highest.

Hana Yori Dango (Jap), Boys Over Flower(Kor) and Meteor Garden (Twn) are all F4 Series.
It also catapulted the main casts to full stardom.
Shun Oguri, Jun Matsumoto, Shot Matsuda, Tsuyoshi Abe made their mark. Shun Oguri and JM were my fav Jap idols. Love Shun on Nobunaga Concerto and Rich Man, Poor Man.
The Korean version boasts an array of good-looking casts, Lee Min-ho, Jonghyun, Kim Bum and Kim Joon. After BOF's high ratings and popularity, these boys were literally put to pedestals.
My favorite version, of course, is the Taiwanese version of Jerry Yan, Vaness Wu, Ken Chu, Vic Chou and of course Barbie Hsu. Jerry Yan, Vaness Wu and the rest of Meteor Garden cast became international celebrities.

And now the new Meteor Garden. Seen the first 5 episodes. My verdict is that Dylan Wang will be the next Lee Min-Ho/Jerry Yan. This will also open up doors for Darren Chen and the rest of the main casts (Liang Kang, Shen Yue and Wu Xi Ze). So far so good, I like the new take, it's fast and crisp, the casts are not only really hot good-looking but are good actors too. And BTW the OSTs were dope too.
