this was brilliant. i loved it so much and it got me so engaged, there wasn't a moment where this film didn't have my full attention. i'll rewatch this again some time and for those who like zombie/thriller movies, this is definitely a must watch! i watched this with my family and everyone loved it. Also got to love Gong Yoo (has to be one of my favourite Korean actors/actors of all time. Every character played a big part, nothing was meaningless although the tension and angst did make me shout at the characters quite a few times. i really could not recommend this enough. it was also really funny, i don't know what else i could've asked for.
