Amazing drama so far. Yeah, the style isn't that great, but for ME this don't interfere with the fact that this is a fun and pretty interesting k drama.
Pretty solid so far, don't bother with the haters here. You can see that some didn't even watched the show -- which is becoming typical of them. I wonder why people bother to criticize something that they didn't even watched. If it's a critique of something you didn't liked watching the show, ok. But why lie about something you haven't watched?
Very likely that will be good, since it's the same writer as signal.
Final episode was pretty mid, tho.
