I watched Meteor Garden, Hana Yori Dango, and the anime, and read the manga.........
And I have to say, Boys Over Flowers was the worst adaptation.

Reasons why this drama was terrible:
1) The main characters did not have any chemistry at all
2) Did not follow the story...big mistake!!
3) The acting was terrible!!!!!!

Reasons why I watched this drama:
1) The second main characters
2) OST
3) One of my favourite manga

Hope the next adaptation is good, and will follow the manga!!!
