JAPANESE:
Maou - Seen, was pretty good no complaints on story, acting was a little stiff in places.
Crisis - Not seen yet will give it a go.
N no tame ni - Not seen yet will give it a go as well.
Cold case - While I should have been a fan of this I found it quite boring, never made it past episode 2.
Kazoku game - Brillitant show, Sakurai Sho does a great job in this one.
The quiz show 2 - I'm going to assume The Quiz Show 1 comes included on this recommendation? Seen it on quite a few times on sites but thought it might be too tongue and cheek.
Ryusei no kizuna - I think I've tried watching this one before, not entirely sure though, will give it another go.
Orthros no Inu - I've seen a similar drama where a boy has the power to heal and in the end he dies saving someone, is this one similar?
Liar game - Same thoughts on this as Quiz Show.
KOREAN:
Signal - Seen it, loved it, would recommend it to anyone who asks for anything in that genre.
Voice - Loved it more than Signal, would again recommend anyone to watch it.
Lookout - While it's supposed to be a darker drama with people overcoming their demons it's just not, too lighthearted and not gritty enough in my opinion.
Tunnel - Nowhere near as good as Signal and Voice, has a pretty ok storyline but I feel like the story comes second fiddle to the characters over dramatizing every detail.
