Happiness was great. If you have Netflix, watch it. Great horror thriller with a virus turning people into a cross between modern zombies and vampires, with a bunch of people trapped in an apartment building - and some of the residents are as dangerous as the monsters. All this and even a rather touching little love story between the two very likeable leads. That's two Korean shows I've seen this year that are better than 99% of anything coming out of the US or UK lately...
