Bloody Monday [ブラッディ・マンデイ] Its very different from the usual jdorama plots. The suspense kills me, and the acting is very nice. I really like all the actors (Miura, Sato, and Kichise especially), so its amazing for me.
Hanazakari no Kimitachi e [花ざかりの君たちへ] It was so enjoyable and entertaining. The drama focuses more on humor, and it delivers it well. All the students were unique and entertaining in their own way, and I thoroughly enjoyed it... except for the fact that they portrayed Sano as a complete jerk.
ROOKIES [ルーキーズ] Its your typical every-drama storyline of a teacher and some delinquents, but this drama made it seem different. Maybe it was baseball, maybe it was the acting, but this drama was amazing for such a overused storyline.
