Here are some of my random opinions and thoughts:
Hana Kimi-my first drama (I personally think it's WAY better than the taiwanese version) that got me hooked to watching dramas~ x]
Gokusen-despite being extremely repetitive and predictable (there were moments where I'd roll my eyes), I couldn't stop watching this corny show. (and even watched Gokusen2).
Nodame Cantabile-WAY better than the manga. I personally think it's the BEST jdrama I've ever watched. PLUS the music elements in it make it extremely tantalizing (I have a thing for good music) and Chiaki makes it even more so. x]
Proposal Daisakusen-one word: SWEEET <3
Goong I usually don't like Kdramas (probably because the ones I came upon weren't so entertaining), but this one was addicting and I love the oriental design in the palace. I also loveee Shin-goon x] (yep, I'm quite onesided. I was SO happy that Chaegyung likes Shin instead of Yul)

I LOVE Manga!

The Bride of the Water God- it totally changed my idea of manhwas~ it's beautifully drawn and the plot is unique and intricate unlike a lot of manhwas..too bad I can't find the rest of it online ever since it was licensed >.<
